Of course, there are tricks when re-publishing. The maximum hop count is still 15 hops Track 1 rtr 1 reachability Router ospf 1 Router ospf 1 No ipv6 rip RIPprocess enable All options are longer than or equal to 0 Routing feedback Neighbor 2001:12::1 remote-as 100 Image Routing time: The time elapsed since the last time the routing entry was modified. The routing time is reset to 0 each time the routing entry is modified . [Test 2 ] PE1 , P , and PE2 form an LDP neighbor relationship and deliver IGP labels. In order to facilitate the observation of experimental phenomena, the label range of PE1 is set to Image Image ! R2 RIPv2 [Experiment 2 ] Both IPv6 islands use ordinary IPv6 global addresses.

Then the routing table of R2 is as follows: Image The example here is DHCPv6 , using Router as the DHCPserver Ipv6 address 2001:0001::FFFF/64 ipv6 rip RIPprocess enable The PC receives an RA message and will do a test: Via FE80::5C10:8CFF:FEE0:FE89, Serial0/0 Redis static route-map cisco Ip route 3.3.3.0 255.255.255.0 serial 0/1 Here are a few concepts to make clear: 20 This path. And because there is no RIP route in the routing table , the natural RIP re-release to OSPF fails, and even worse, R4 about Image Ipv6 address 2001:12::1/64 Interface loopback0 Ip address 202.101.100.1 255.255.255.0 Mpls label range 400 499 mpls ldp router-id Loopback0 By using route tags in RIP , you can control the redistribution of related routes in other protocols. When republishing to other protocols, RIP routes simply compare the tokens assigned to them without comparing the entire route. Version Single match includes a plurality of conditional statements, logical or operation; multiple match when the statement, using the logic and operation. Now, let’s go to R1 again. IGRP 0x0000000E Image Note that the 6to4 tunneling technology does not support dynamic routing protocols. OR2 configuration When debugging , you can open debug ipv6 nd Image ! Ipv6 unicast-routing interface Loopback0 "Double-point bidirectional" routing re-release is a simple model that can often be used in large networks. For example, in a financial network, if a dynamic routing protocol is run between a secondary line and a branch router, then this model may be involved. The so-called two-point bidirectional refers to a node with two routes re-issued on the boundary of two routing domains, and the direction of re-distribution is bidirectional. For example, in the above figure, the secondary line has two aggregation routers for access to the following outlets or branch routers. Then the two routers are two-point. In addition, in order to make the routes of the entire network reachable, two-way routing re-distribution is deployed on the two routers, that is, OSPF is re-released to RIP , and RIP is also re-released to OSPF. .
