As shown in the figure, in a medium-sized network, BGP generally deploys dual RRs to improve R reliability. When deploying dual RRs, the ClusterIDs of the two RRs are generally set to be the same. What is the reason for this?

Prevent RR from receiving too many routes and causing insufficient memory

Prevent the client from receiving too many routes and causing it to run out of memory

A campus has deployed IPv6 for service testing. There are 4 routers in the network, running 0SPFv3 to implement IPv6 network interconnection. As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs. Which of the following statements is true about the description of this LSA?

The router that generates this LSA is R2 port R2 connected

IPv6 address prefix for GEO/0/0: 2001:DB8:2345:23::/64

The link-local address of R2 interface GEO/0/0 is: FE80::2E0:FCFF:FEC, D:4F79

When there are multiple redundant links in the IS-S network, multiple equal-cost routes may appear. Which of the following statements is false about equal-cost routing within an IS-IS network?

After configuring equal-cost route priorityJS-ISWhen the device forwards the traffic reaching the destination network segment, it will not adopt the load balancing method, but forward the traffic to the next hop with the highest priority

When the number of equal-cost routes in the network is greater than the number configured by the command, and these routes have the same priority, Preferred next hop deviceSystem IDLarge routes for load balancing

If load sharing is configured, the traffic will be evenly distributed to each link

After configuring equal-cost route priorityJS-ISWhen the device forwards the traffic reaching the destination network segment, it will not adopt the load balancing method, but forward the traffic to the next hop with the highest priority

For each route in the equal-cost route, a priority can be specified, and the route with higher priority will be preferred. the rest as backup routes

Root description of the current network

In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.label, the description of the two-layer label in the following options is wrong

MPLS VPNEThe outer layer label is called the private network label, and the inner layer label is called the public network label

MPLS VPNThe outer label is made byLDPprotocol or statically assigned, the inner label is assigned by the correct end MP-BGPassigned by neighbors

MPLS VPNEThe outer layer label is called the private network label, and the inner layer label is called the public network label

By default, the outer label is singled out before the packet is forwarded to the last hop device

An engineer uses two routers to test IPv6 services, and simulates the interconnection between the headquarters and branches by running BGP4+. The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between the two devices, which of the following Is a statement wrong?

The Next_Hop attribute must be an IPv6 global unicast address when routing

BGP4+ transmits routing information between peers through Update packets

If the MP_REA, CH_NLRI attribute is carried in the Update packet, it indicates that the advertisement is a reachable route

When the route is transmitted, it will carry recognized mandatory attributes such as AS_Path
