RIP version number: Now do a test, R1 on the ping www.ccietea.com , we will find: OK , now go back to the main class network number 172.16.0.0/16 , then we will go out and look at the picture. 172.0.0.0/8 actually shifts the mask of this class B address to the left by 8 bits , so that the network number obtained is actually a large network number including 172.16.0.0/16 . Call it supernet . Image Distance 130 2.2.2.2 0.0.0.0 1 ! Activate the RIPng process and interface Address does not need R2 will use the primary address and the secondary address for validate-update-source , so R2 can learn 2.2.2.0 and 3.3.3.0 routes. When 10.4.0.0 is hanged , C will immediately send a route poisoning message ( 10.4.0.0 16 hops) and then advertise it; ipv6 nat v6v4 source 2001: 1 :: 1 202.101.100.100 !! equivalent to 2001: 1 :: 1 this IPv6 node, "told" to IP protocol number 88 Command First define the track object , associated with an ip sla monitor Configure static routes by using the associated outbound interface. Match tag matches based on the tag of the route Complete basic IP configuration In addition, IS-IS neighboring routers have a very important factor to consider. In an IPv4 or IPv6 single-protocol environment,ccna exam topics, IS-IS adjacencies and information interactions are not problematic. However , care should be taken when enabling both protocols ( IPv4 and IPv6 ) on all neighboring IS-IS routers . In this particular case, the two protocols must be enabled on all IS-IS neighboring routers. Otherwise, the IS-IS router will no longer maintain the adjacency relationship with all its IS-IS IPv4 neighbors. In fact, when Level1 or Level1-2 IS-IS router in adjacency checking is enabled, it checks from the IS-IS the neighbor Hello message, if the neighbor to use a different set of protocols, it refused abutting relationship therewith.
