Redistribute rip subnets tag 1111 OSPFv3 uses the IPv6 Linklocal address to identify OSPFv3 neighbors. Ipv6 nat Image Group-ID This field can be 112 bits long to identify multicast groups, and 112 bits can generate up to 2112 group IDs . Neighbor 2001:45::4 remote-as 234 Interface serial0/0 3.0 this route. This is an example of the use of a distribution list. Of course, it has a wider range of applications. Conduct a three-layer forwarding decision. The CEF table maintains core information extracted from the routing table, which is used to perform forwarding decisions on received messages, including IP prefixes, recursive next hop addresses, and outbound interfaces. An important feature of the CEF table is its ability to make immediate decisions about recursive prefixes. URL representation of the IPv6 address Network 3.3.3.0 mask 255.255.255.0 1/0/0 25 729 Other configuration The configuration of R2 is as follows: NDP can help us achieve the following features: It can be seen from the CEF table that when PE1 receives the traffic from CE1 to CE2 at 2001:5555::5 , the label is compressed by two layers,cisco ccna questions, and the outer layer is 301 , which is distributed by the P router, and the inner layer is 403 . PE1 is distributed. ::FFFF: 4.4.4.4 IP routing overview Image R1#show ip bgp ipv6 unicast summary Route-map cisco permit 20 match ip address 2 set metric 10 Ip address 202.101.23.3 255.255.255.0 FastEthernet1/0 Image The problem is similar to that mentioned above. Both R2 and R3 can learn to update the BGP B network segment route from R4 . Suppose R2 republish do first, then B routes will be injected into the OSPF , the finally R3 learned, then R3 , the same time from the OSPF and IBGP learned this route, will preferably OSPF , since OSPF is AD smaller. As a result, on R3 , the redistribution of IBGP to OSPF fails because the route of the B network segment is not BGP in the routing table . Furthermore, R3 has been re-released in both directions. Therefore , the route of the B network segment will be re-released back to IBGP . Since then, there may be a series of problems such as sub-optimal paths and loops.
