Interface Serial0/0 ipv6 enable Bgp router-id 2.2.2.2 !! Connect A to the interface Difficult analysis Here we use a access-list 1 match 202.101.100.0/24 network, while it with v4v6-pool this IPv6 address pool to do a bundle Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 Isis Ip cef Y *> 2001:12::/64 The configuration of R2 is as follows: On this topic, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved, and you are interested in making it yourself. Access-list 1 permit 10.1.1.0 Exit-address-family Router rip At this point , the route 1.1.1.0 is seen on R3 , which contains the next hop attribute, and the previous one. Access-list 2 permit 10.1.2.0 route-map cisco permit 10 Eliminate routing loops by horizontal splitting ... partially omitted ... Multilink Multilink-group interface Index 1/1/1, retransmission queue length 0, number of retransmission 0 First 0x0(0)/0x0(0)/0x0(0) Next 0x0(0)/0x0(0)/0x0(0) !! When the route matching ACL1 when Provides information about the existence and lifetime of the default router IPv6 address. In IPv6 , the default router address used by the node is the linklocal address of the router ,ccna certification exam, so that even if the prefix is readdressed , the default gateway is reachable ( linklocal) Ipv6 unicast-routing interface Tunnel0 RIP based on rumor updates description At another point, R2 will take 10.0.0.0 , 11.0.0.0 (the network segment where the secondary address is located), and 1.0.0.0 and 3.3.3.0 from their own loopback. When the link between R1 and R3 fails, the same network will still have problems. Because R2 re-releases the locally configured static summary route into the Image Ipv6 nd managed-config-flag RS requires the router to generate RA immediately !! The red font part is the number of hops to be increased Ip rip trigger In fact, there are two main lifetimes of IPv6 addresses , one is Valid lifetime and the other is preferred lifetime . First in You can configure a CISCO router as a 6to4 relay with an arbitrary IPv4 prefix : PE1 and PE2 activated between MPBGP neighbor relations, to pass VPNv6 ready prefix RIP version number: Prefix announcement Interface Loopback0 The configuration of R2 is as follows: Address-family ipv6 Image The configuration of R1 is as follows: IPv6 header replace IPv4 header prior to forwarding to B . PS : It should be noted that there will be class and classless route lookup methods, which are distinguished from classful and classless routing protocols. A and B respectively use this IPv4 public network address to map to get the 6to4 address space. The 6to4 address space uses 2002::/16 , and the 6to4 address is formed as follows: First ensure that R1 , R3 to 10.1.1.0 are routed, and test on R2 : RFC1058 The example here is DHCPv6 , using Router as the DHCPserver After changing the topology, the interface IP of R2 has changed. At this time , the RIP sent by R1 is updated, and the source address is still 192.168.12.1 . After receiving R2 , it finds that the interface IP that is updated with the local is not in a subnet, so R2 ignores the update message of R1 . In addition, the message sent by R2 to R1 is accepted by R1 , because R1 thinks that the RIP update message source address 192.168.12.5 sent by R2 is on the same subnet as its own interface.
