(Choose three.)  delete protocols isis export summary-v6  set protocols isis import summary-v6  delete policy-options policy-statement summary-v6 term DC-routes from route-filter2001:db5:a:fa00::/61 longer  set policy-options policy-statement summary-v6 term DC-routes from route-filter2001:dbS:a:fa00::/6l exact  set policy-options policy-statement summary-v6 term suppress then reject NEW QUESTION 46R4 is directly connected to both RPs (R2 and R3). R4 is currently sending all joins upstream to R3 but you want all joins to go to R2 instead.Referring to the exhibit, which configuration change will solve this issue?  Change the bootstrap priority on R2 to be higher than R3.  Change the local address on R2 to be higher than R3.  Change the default route in inet.2 on R4 from R3 as the next hop to R2.  Change the group-range to be more specific on R2 than R3. NEW QUESTION 47ExhibitCE-1 must advertise ten subnets to PE-1 using BGP Once CE-1 starts advertising the subnets to PE-1, the BGP peering state changes to Active.Referring to the CLI output shown in the exhibit, which statement is correct?  CE-1 is advertising its entire routing table.  CE-1 is configured with an incorrect peer AS  The prefix limit has been reached on PE-1  CE-1 is unreachable ExplanationThe problem in this scenario is that CE-1 is configured with an incorrect peer AS number for its BGP session with PE-1. The CLI output shows that CE-1 is using AS 65531 as its local AS number and AS 65530 as its peer AS number. However, PE-1 is using AS 65530 as its local AS number and AS 65531 as its peer AS number. This causes a mismatch in the BGP OPEN messages and prevents the BGP session from being established. To solve this problem, CE-1 should configure its peer AS number as 65530 under [edit protocols bgp group external] hierarchy level.NEW QUESTION 48ExhibitReferring to the exhibit, a working L3VPN exists that connects VPN-A sites CoS is configured correctly to match on the MPLS EXP bits of the LSP, but when traffic is sent from Site-1 to Site-2, PE-2 is not classifying the traffic correctly What should you do to solve the problem?  Configure the explicit-null statement on PE-1.  Configure the explicit-null statement on PE-2  Configure VPN prefix mapping for the PE-1_to_PE-2 LSP  Set a static CoS value for the PE-1_to_PE-2 LSP The explicit-null statement enables the PE router to send an MPLS label with a value of 0 (explicit null) instead of an IP header for packets destined to the VPN customer sites. This allows the penultimate hop router (the router before the egress PE router) to preserve the EXP bits of the MPLS label and pass them to the egress PE router. The egress PE router can then use these EXP bits to classify the traffic according to the CoS policy2. In this example, PE-1 should configure the explicit-null statement under [edit protocols mpls label-switched-path PE-1_to_PE-2] hierarchy level.NEW QUESTION 49ExhibitReferring to the exhibit, you must provide Internet access for VPN-A using CE-1 as the hub CE.Which two statements are correct in this situation? (Choose two.)  You must use RIB groups to leak routes between the inet. o and vpn-a. inet. o tables.  RIB groups are not needed to leak routes between the inet. 0 and VPN-A. inet. 0 tables,  Internet traffic from Site 2 takes the path of PE-2 -> PE-1 -> GW-1.  Internet traffic from Site 2 takes the path of PE-2 -> PE-1 -> CE-1 -> PE-1 -> GW-1. ExplanationTo provide Internet access for VPN-A using CE-1 as the hub CE, you need to do the following:* You must use RIB groups to leak routes between the inet.0 and vpn-a.inet.0 tables on PE-1 and CE-1.RIB groups are routing options that allow you to import routes from one routing table into another routing table based on certain criteria. In this scenario, you need to configure RIB groups on PE-1 and CE-1 to import Internet routes from inet.0 into vpn-a.inet.0 and vice versa.* Internet traffic from Site 2 takes the path of PE-2 -> PE-1 -> CE-1 -> PE-1 -> GW-1. This is because Site 2 does not have direct Internet access and needs to use CE-1 as its default gateway for Internet traffic. Site 2 sends its Internet traffic to PE-2, which forwards it to PE-1 based on VPN-A routes. PE-1 then sends it to CE-1 based on RIB group import policy. CE-1 then sends it back to PE-1 based on its default route pointing to GW-1. PE-1 then forwards it to GW-1 based on RIB group import policy again.NEW QUESTION 50When building an interprovider VPN. you notice on the PE router that you have hidden routes which are received from your BGP peer with family inet labeled-unicast configured.Which parameter must you configure to solve this problem?  Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.  Under the protocols mpls hierarchy, add the traffic-engineering parameter.  Under the family inet labeled-unicast hierarchy, add the explicit null parameter.  Under the protocols ospf hierarchy, add the traffic-engineering parameter. NEW QUESTION 51Which two statements are correct about VPLS tunnels? (Choose two.)  BGP-signaled VPLS tunnels require manual provisioning of sites.  LDP-signaled VPLS tunnels only support control bit 0.  LDP-signaled VPLS tunnels use auto-discovery to provision sites.  BGP-signaled VPLS tunnels can use either RSVP or LDP between the PE routers. NEW QUESTION 52ExhibitReferring to the exhibit, PE-1 and PE-2 are getting route updates for VPN-B when neither of them service that VPN Which two actions would optimize this process? (Choose two.)  Configure the family route-target statement on the PEs.  Configure the family route-target statement on the RR  Configure the resolution rib bgp . 13vpn . 0 resolution-ribs inet. 0 Statement on the PEs.  Configure the resolution rib bgp.l3vpn.O resolution-ribs inet. 0 Statement on the RR ExplanationBGP route target filtering is a technique that reduces the number of routers that receive VPN routes and route updates, helping to limit the amount of overhead associated with running a VPN. BGP route target filtering is based on the exchange of the route-target address family, which contains information about the VPN membership of each PE device. Based on this information, a PE device can decide whether to accept or reject VPN routes from another PE device.BGP route target filtering can be configured on PE devices or on route reflectors (RRs). Configuring BGP route target filtering on RRs is more efficient and scalable, as it reduces the number of BGP sessions and updates between PE devices. To configure BGP route target filtering on RRs, the following steps are required:* Configure the family route-target statement under the BGP group or neighbor configuration on the RRs.This enables the exchange of the route-target address family between the RRs and their clients (PE devices).* Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement under the routing-options configuration on the RRs. This enables the RRs to resolve next hops for VPN routes using the inet.0 routing table.* Configure an export policy for BGP route target filtering under the routing-options configuration on the RRs. This policy controls which route targets are advertised to each PE device based on their VPN membership.NEW QUESTION 53ExhibitYou are attempting to summarize routes from the 203.0.113.128/25 IP block on R8 to AS 64500. You implement the export policy shown in the exhibit and all routes from the routing table stop being advertised.In this scenario, which two steps would you take to summarize the route in BGP? (Choose two.)  Remove the from protocol bgp command from the export policy.  Add the set protocols bgp family inet unicast add-path command to allow additional routes to the RIB tables. –  Add the set routing-options static route 203.0.113.123/25 discard command.  Replace exact in the export policy with orlonger. ExplanationTo summarize routes from the 203.0.113.128/25 IP block on R8 to AS 64500, you need to do the following:* Add the set routing-options static route 203.0.113.128/25 discard command. This creates a static route for the summary prefix and discards any traffic destined to it. This is necessary because BGP can only advertise routes that are present in the routing table.* Replace exact in the export policy with orlonger. This allows R8 to match and advertise any route that is equal or more specific than the summary prefix. The exact term only matches routes that are exactly equal to the summary prefix, which is not present in the routing table.NEW QUESTION 54A router running IS-IS is configured with an ISO address of 49.0001.00a0.c96b.c490.00.Which part of this address is the system ID?  c96b.c490 is the system identifier.  c490 is the system identifier.  00a0.c96b.c490 is the system identifier.  0001.00a0.c96b.c490 is the system identifier. NEW QUESTION 55You are configuring an interprovider Option C Layer 3 VPN to connect two customer sites.Referring to the exhibit, which three statements are correct? (Choose three.)  ASBR routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.  ASBR routers maintain the internal routes from its own AS and the loopback addresses from the other AS PEs.  P routers maintain the internal routes from its own AS and the loopback address from the other AS PEs.  P routers only maintain the internal routes from their own AS.  PE routers maintain the internal routes from its own AS, the loopback address from the other AS Pes, and the L3VPN routes. NEW QUESTION 56You are responding to an RFP for a new MPLS VPN implementation. The solution must use LDP for signaling and support Layer 2 connectivity without using BGP The solution must be scalable and support multiple VPN connections over a single MPLS LSP The customer wants to maintain all routing for their Private network In this scenario, which solution do you propose?  circuit cross-connect  BGP Layer 2 VPN  LDP Layer 2 circuit  translational cross-connect AToM (Any Transport over MPLS) is a framework that supports various Layer 2 transport types over an MPLS network core. One of the transport types supported by AToM is LDP Layer 2 circuit, which is a point-to-point Layer 2 connection that uses LDP for signaling and MPLS for forwarding. LDP Layer 2 circuit can support Layer 2 connectivity without using BGP and can be scalable and efficient by using a single MPLS LSP for multiple VPN connections. The customer can maintain all routing for their private network by using their own CE switches.NEW QUESTION 57After a recent power outage, your manager asks you to investigate ways to automatically reduce the impact caused by suboptimal routing in your OSPF and OSPFv3 network after devices reboot.Which three configuration statements accomplish this task? (Choose three.)  set protocols ospf overload timeout 900  set protocols ospf3 realm ipv4-unicast overload timeout 900  set protocols ospf overload  set protocols oapf3 overload timeout 900  set protocols ospf3 overload ExplanationTo reduce the impact of suboptimal routing in OSPF and OSPFv3 after devices reboot, you can use the overload feature to prevent a router from being used as a transit router for a specified period of time. This allows the router to stabilize its routing table before forwarding traffic for other routers. To enable the overload feature, you need to do the following:* For OSPF, configure the overload statement under [edit protocols ospf] hierarchy level. You can also specify a timeout value in seconds to indicate how long the router should remain in overload state after it boots up. For example, set protocols ospf overload timeout 900 means that the router will be in overload state for 15 minutes after it boots up.* For OSPFv3, configure the overload statement under [edit protocols ospf3] hierarchy level. You can also specify a realm (ipv4-unicast or ipv6-unicast) and a timeout value in seconds to indicate how long the router should remain in overload state after it boots up for each realm. For example, set protocols ospf3 realm ipv4-unicast overload timeout 900 means that the router will be in overload state for 15 minutes after it boots up for IPv4 unicast routing.NEW QUESTION 58A network is using IS-IS for routing.In this scenario, why are there two TLVs shown in the exhibit?  There are both narrow and wide metric devices in the topology.  Both IPv4 and IPv6 are being used in the topology.  Wide metrics have specifically been requested.  The interface specified a metric of 100 for L2. NEW QUESTION 59You must ensure that the VPN backbone is preferred over the back door intra-area link as long as the VPN is available.Referring to the exhibit, which action will accomplish this task?  Enable OSPF traffic-engineering.  Configure an import routing policy on the CE routers that rejects OSPF routes learned on the backup intra-area link.  Create an OSPF sham link between the PE routers.  Configure the OSPF metric on the backup intra-area link that is higher than the L3VPN link. NEW QUESTION 60You have an OSPF environment. You have recently added a router called R4 that is directly connected to R1 and R2. You discover that R4 is only peering with R2.Referring to the exhibit, how would you correct the peering?  Adjust the Hello Interval on R1 and R2 to match the Hello Interval on R4.  Change the MTU size on R1 and R2 to be 22 bytes higher than R4’s MTU size.  Adjust the Dead Interval on R4 to match the Dead Interval on R1 and R2.  Adjust the Priority on R1 to be lower than the Priority on R4. NEW QUESTION 61ExhibitReferring to the exhibit, CE-1 is providing NAT services for the hosts at Site 1 and you must provide Internet access for those hosts Which two statements are correct in this scenario? (Choose two.)  You must configure a static route in the main routing instance for the 10 1 2.0/24 prefix that uses the VPN-A.inet.0 table as the next hop  You must configure a static route in the main routing instance for the 203.0.113.1/32 prefix that uses the VPN-A.inet.0 table as the next hop.  You must configure a RIB group on PE-1 to leak a default route from the inet.0 table to the VPN-A.inet.0 table.  You must configure a RIB group on PE-1 to leak the 10 1 2.0/24 prefix from the VPN-A.inet.0 table to the inet.0 table. NEW QUESTION 62Your organization manages a Layer 3 VPN for multiple customers To support advanced route than one BGP community on advertised VPN routes to remote PE routers.Which routing-instance configuration parameter would support this requirement?  vrf-export  vrf-import  vrf-target export  vrf-target import The vrf-target export parameter is used to specify one or more BGP extended community attributes that are attached to VPN routes when they are exported from a VRF routing instance to remote PE routers. This parameter allows you to control which VPN routes are accepted by remote PE routers based on their import policies. You can specify more than one vrf-target export value for a VRF routing instance to support advanced route filtering or route leaking scenarios. Loading … Verified JN0-664 dumps Q&As Latest JN0-664 Download: https://www.actualtests4sure.com/JN0-664-test-questions.html --------------------------------------------------- Images: https://blog.actualtests4sure.com/wp-content/plugins/watu/loading.gif https://blog.actualtests4sure.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2024-05-13 10:16:30 Post date GMT: 2024-05-13 10:16:30 Post modified date: 2024-05-13 10:16:30 Post modified date GMT: 2024-05-13 10:16:30
