On R2 , you can also see the following error: Image Route-map Subnet router anycast address: UNICAST_PREFIX : 0:0:0:0 Experiment 3 2204 Interface Serial0/0 ipv6 enable 101x xxxx xxxx xxxx Show vrf ipv6 view vrf ipv6 RIPv2 manual summary Image Ipv6 router ospf 1 router-id 2.2.2.2 The configuration of R1 is as follows: If you want to tunnel two IPv6 IS-IS islands using tunneling , you need to use a GRE tunnel. Image The following is our CE1 , ping 2001:5555::5 , then capture the packet on the Fa1/0 port of PE1 : RIP defines two types of request messages and response messages. Equivalent to see the ARP table, in fact, is the neighbor cache table The cache extracts the destination interface , destination MAC address, etc. , which greatly speeds up packet forwarding. (Of course, in the case of FA=0.0.0.0 ), then, in this figure, if the cost of R2 to ASBR-R3 is smaller, the final R2 will be preferred.

In R1 the ip default-network 172.16.0.0 R1#sh ipv6 route ospf Ipv6 router ospf 1 router-id 1.1.1.1 Cisco CEF is the most efficient three-layer protocol. CEF uses a hardware-based platform . It not only stores data in the system buffer, but also " prestores " the entire routing table, topology table , and all next hop addresses and MAC addresses , as long as the routing table, The entries in the topology table , regardless of whether there is a data request sent to its destination address , will be pre-read in advance , pre-set the cache . Thus , when there is a new data request to send , the CPU is not required to query the destination interface , destination MAC Address and other information , but read directly from the cache , so the forwarding speed is greatly improved .
