NEW QUESTION 110Which 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 genericrouting 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 provideredge (SPE) is insufficient, a user-end provider edge (UPE) can be added and the SPE moved to a lowerlayer. 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 connectedthrough 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 representedby a default route or an aggregate route, reducing the load of the SPE.
