following can be used to avoid routing loops when RTA generate an autonomy system-external (ASE)
link-state advertisement (LSA) and sends it to the CE?

Configuring the same domain ID on the PE

NEW QUESTION 88
Which of the following statements about the VPLS packet forwarding are true?

If a PE receives broadcast packets from a local user, the PE forwards the packets to all other interfaces
In the same VSI and all other PEs.

If the destination MAC address of a packet is not a broadcast address and a PE has not learned the MAC
address, the broadcast this packet in one VSI

If the destination MAC address of a packets is not a broadcast address and a PE has not learned the
MAC address, the PE broadcast this packet in on VSI.

If a receive broadcast packet sent a remote PE, it forwards the packet only to the AC interface instead of
other PEs.

NEW QUESTION 89
Which of the following statements about control words in the L2VPN are true?

When SVC VLL is used, if PEs at two ends of a VC use different control words, the may not become Up.

When Martini VLL is used, if PEs at two ends of a virtual connection (VC) use different control words, the VC may not become Up

The control word can be used to identically the packet sequence.

A control word generally has two bytes and can ne extended to four bytes.

The control word can be used for packet padding For example, when the public network uses Ethernet and the AC uses Peer-to-protocol (PPP), control words can be used to transfer and identify PPP packet with a bytes.

NEW QUESTION 107
The RADIUS or Huawei Terminal Access Controller Access Control System (HWTACACS) protocol can be used for authentication during network access. Which of the following statements about these two protocols are false?

The HWTACACS uses TCP to transmit data while the RADIUS uses UDP to transmit data.

Both the HWTACACS and RADIUS encrypt all data in the packet body.

The domain ID in the BGP route is the same as that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 1 LSA and send it to CE 2.

The domain ID in the BGP route is the same as that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 3 LSA and send it to CE 2.

The domain ID in the BGP route is the same as that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 5 LSA and send it to CE 2.

The domain ID in the BGP route is different from that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 5 LSA and send it to CE 2.

NEW QUESTION 110
Which of the followingstatementsabout the merits of the HoVPN networking are true?

If the UPE are SPE are separated by an IP/IPMLS network, they can be connected through a generic
routing encapsulation (GRE) or LSP runnel . A hierarchical MPLS VPN provides good scalability.

The SPE and UP exchange routes and advertise labels through MP-BGP. Each UPE runs only one –
BGP peer, reducing system overheads and simplifying configuration.

The BGP/MPLS VPN can be deployed layers by layer. When the performance of a super strum provider
edge (SPE) is insufficient, a user-end provider edge (UPE) can be added and the SPE moved to a lower
layer. When the access capability of a UPE is insufficient, and SPE can be added.

Packets are forwarded between a UPE and an SPE after being label. The UPE and SPE are connected
through an interface (or a subinterface), helping reduce the usage of limited interface resources.

Only local VPN routes need to be maintained on an SPE and remote routes on the SPE are represented
by a default route or an aggregate route, reducing the load of the SPE.
