Ipv6 address FE80::FFFF:FE10:1 link-local The BGP4+ configuration of R2 is as follows: None Image FF02::2 link local range all router multicast addresses The destination IP address of the route can only be the address of the natural network segment. meaning Redistribute routes to the protocol Neighbor 2.2.2.2 Mpls ldp router-id Loopback0 mpls label range 300 399 Routing strategy needs (reliability, redundancy,cisco ccna certification, offloading model, etc.) R4 released the RIP route of 100.1.1.0/24 , which can be learned by both ASBRs . The solution is to configure static summary routes on the two ASBRs : Used to limit the time that the route staying in the routing table has not been updated. DC Another recommended solution is to adjust the management distance of the routing protocol: Metric value: The overhead of the router to reach the destination is an integer between 0 and 15 . R3 Foundation Detailed mechanism Detect the reachability of the next hop, the default is off Neighbor 2001:12::1 activate exit-address-family CE1 forwards the IPv6 route to PE1 and passes it to PE2 through the MPBGP adjacency between PE1 and PE2 , and finally passes it to CE2 . The IPv6 route delivery from CE2 to CE1 is similar. The ultimate goal of the experiment was reached, passing IPv6 routes through MPLS Backbone . Then both CEs can learn the IPv6 route of the other party. Can our IPv6 data cross the Core ? After all, Core is non- IPv6 and has no IPv6 routing. At this time, the power of MPLS has come into play. When data between sites is transmitted in the MPLS Backbone , it is mostly a two-layer label, and the outer layer is LDP.The generated inner layer is generated by MPBGP for IPv6 routes.
