Deception process ARP Response !! This is the direct link between R1-R3 If the prefix does not match any entry in the prefix list, it will be rejected BGP router identifier 10.1.13.3, local AS number 345 14 * 172.16.0.0/16 is variably subnetted,ccnp route outline, 4 subnets, 2 masks S* 172.16.0.0/16 [1/0] via 172.16.3.0 Strictly speaking, path control is a very big topic. In the deployment of a large network, it is often necessary to consider the control of the data traffic access path in order to make more rational and scientific use and allocation of network resources. At the same time, it enhances the reliability, redundancy and robustness of the network. The preferred principle is IGP > EGP > Incomplete Note that with route-map , the last is implicitly killing any , while the suppress-map is different. 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.
