ccna routing

Switched Track 1 rtr 1 reachability !! Core in OSPF Advanced features Image R2 to R1 added IPv4 header removed to restore the original IPv6 data, and then forwarded to the right of the IPv6 PC . Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 ! Redistribute connected subnets redistribute rip metric 10 subnets Untagged Image Network 3.3.3.0 mask 255.255.255.0 Frame-relay map ipv6 FE80::5C10:8CFF:FEE0:FE89 102 broadcast Unassigned A quick look at: Ipv6 address FE80::FFFF:FE10:6 link-local ipv6 router isis 3 jumps. One of the ideal solutions is to transform the network topology: 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,ccna routing, there may be a series of problems such as sub-optimal paths and loops.
