Configure the DHCP client and specify the prefix name obtained as test (local valid) Remarks Y Do not use prefix for autoconfiguration When R2 is configured with no validate-update-source , R2 will not verify the RIP update message source, so R2 will accept R1.

Ipv6 unicast-routing Experimental test Neighbor 2001::1 next-hop-self Ip route 10.1.2.0 255.255.255.0 10.1.254.1 Cannot be included in route calculation The router interface is configured with new and old prefixes, and both are advertised. The old prefix has a shorter lifetime, so that the nodes in the station can use two addresses at the same time. When the old prefix fails, only the new prefix is ​​used. Switching is possible. Note that the 6to4 tunneling technology does not support dynamic routing protocols. Address family Route-target export 234:2 Router ospf1 Neighbor FE80::CE01:8FF:FED8:10 update-source FastEthernet0/0 The O position 1 indicates whether the entry in the NA message overwrites the existing one, and the neighbor who receives the message overwrites the existing entry. !! When the route matching ACL1 when 172.16.10.1 , in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course,ccna wireless dumps, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . 12 !! Interface activates IPv6 FF02::1 link local range all node multicast address Image In order to allow R1 to access the rest of the network, once and for all, send a RIPng default route to R1 : Address format: FF02:0:0:0:0:1:FFXX:XXXX , the specific correspondence is as follows: If ip next-hop and ip next-hop recursive are used in the same sequence of a route-map list , then ip next-hop is valid. If ip next-hop is hanged, ip next-hop recursive is enabled . If ip next-hop recursive and ip next-hop are both hanged, they are thrown to the routing table for processing . Note: A route-map sequence (such as route-map test permit 10 ) allows only one configuration. Distance vector routing protocol The transition mechanism of V4 to V6 discussed above is basically the case where V4 and V6 coexist. So if there is a need for mutual access to the V4 single protocol and the V6 single protocol network? Ipv6 address 2001:34::4/64 Hex Router(config)#router rip In addition, if the R1 update 1.0.0.0 to R2 , if R1passive out and R2 interconnect interface, invalid after the expiration, R2 on about the 1.0.0.0 route will Pdown , then R2 can still go to 1.0.0.0 , but will not Pass this route to other neighbors, instead sending non-stop messages. At this time, if the interface of R1 is passived , R2 will continue to receive the update, but it will not resume the route immediately, but will enter the holddown timer until the holddown timer expires before accepting the update of the route.
