Ipv6 enable The configuration of R2 is similar. After the configuration is complete, the RIP messages are exchanged between R1 and R2 , and the unicast is performed, so that the PC will not be affected. Netsh interface ipv6 add address 21 3ffe::1 unicast !! Assuming that the interface index number to be configured is 21 , this command configures an IPv6 unicast address for the interface .

Ip cef or 202.101.100.100 The MPLS Domain consists of three routers: PE1 , P , and PE2 . The IGP protocol running in the domain is OSPF , and the process ID is 100 . Each of the three routers announces its own loopback port into Core 's OSPF . The address of Loopback is xxxx/32 , and x is the router number, such as PE1 is 2.2.2.2 , P is 3.3.3.3 , and PE2 is 4.4.4.4 .

IPv4- compatible addresses are used for transition mechanisms such as automatic ipv4- compatible tunneling and NAT-PT (see the IPv6 Transition Technology section of this document for details). Reference book ...... Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS IP routing troubleshooting Use the Linklocal address as the source address of the protocol packet and send a RIPng message to the neighboring RIPng router.

Unassigned RIPv1 update and receiving rule verification #源 server Link-layer Addr 1) The above example, A received the IPv4 public network address: 132.214.1.10 , the mapping obtained 2002: 84d6: 010a :: / 48 , part of this address space was eventually used on PC1 . Now, PC1 will send an IPv6 data to PC2 . The source of this data IP is PC1 of FastEthernet1/0 length The configuration of PE1 is as follows: Interface FastEthernet0/0 ipv6 enable If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route. IPv6 address configuration method Image Indicates whether the router is running IPV6 and the packets sent by the router running OSPFv3 . This field is normally set to 1. NDP Neighbor Discovery Protocol ( RFC2461 ) Ip sla monitor 2 The configuration of R2 is added as follows: FF01::2 node local range all router multicast address Ethernet Adjust DAD The R position 1 indicates that this is a router.

In an IPv4 or IPv6 single-protocol environment, 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.
