Ipv6 nat v4v6 source 202.101.100.2 2001:2::2 Virtual-PPP Virtual PPP interface Virtual-Template Virtual Template interface !! Note that this order must be matched because After receiving the packet check, R2 finds that this is the IP of the same subnet as the interface that accepts the update package , so accept this update. Therefore, this test, although the interface masks on both sides are different, but can accept each other's updates, and can also ping between 1.1.1.1 and 2.2.2.2 . Must be zero FastEthernet0/0 Or Tunnel Id Allocated aggregated global unicast address *>i2001:5555::5/128 Image Then do a simple test: !! In the GNS simulator environment, the Linklocal address of the serial port conflicts, because R2 entries ( 2033 :: 3 is R3 is Loopback0 port IP address): Route summary C000 – DFFF Image R3 entry: Difficult analysis Image Level2 router factor Advanced configuration !! This is the direct link between R1-R3 Field name ! Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length Expire prefix at a specific time/date Infinite Valid Lifetime Match interface matches the route with the next outgoing interface as one of the specified interfaces. Link-local address "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,ccna ccnp, 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. .
