Port First come to know the first three-layer interface: SVI switched virtual interface, a logical interface of SVI , that is to say not a physical interface, when we create a VLAN on the switch , we can create a The SVI interface corresponding to the VLAN , for example, we created LOCAL-PREFERENCE RIP also supports tags , but it must be version 2 . Requires trunk link support between switches Configuration example: Then, first R2's own routing table will change, 3.0 routing is filtered out, and R3 is the downstream RIP router, 3.0 can not learn. ( Optional ) VTP Version capable Between ASs , and within AS , BGP hopes that the IGP protocol can be handled by itself, so the administrative distance of IBGP routes is set to a large AD value of 200 . Display BGP tables, for example: Ip community-list 11 permit 100:11 Optional non-delivery, generally used between AS to affect routing. Route-map usage scenario The penalty value of all normal routes is 0 , and the penalty value is added instantaneously. Configure all interfaces as passive and manually activate specific interfaces: Not advertised to any peer By default, the longest matching principle is adopted. If it matches, it will be forwarded. If there is no match, the default route will be found. If the default route is not available, it will be discarded. Choose PAgP or LACP Send TCP packet Undoubtedly, R3 will preferably OSPF the B route, since OSPF the AD small, so that R3 is formed suboptimal paths, which go B segment will choose R1-R2 -R4-R5 this path. Furthermore, in the routing table of R3 , the route on the B network segment is O , then even if R3 does a re-release from RIP to OSPF , the re-release is definitely a failure,ccnp tshoot foundation learning guide pdf, because we have said before, the routing protocol is heavy. The release will only live in the routing table, and the routing table on the B is OSPF , so the re-issue fails.
