Change the metric to 2 ! BVI Bridge-Group Virtual Interface R4#show ipv6 route ospf In a real network environment, we may encounter a situation where there are two or more routing protocols in a network environment, for example: Interface loopback 0 Ipv6 address 2001:1:1::1/64 ipv6 address 2001:1:2::1/64 exit [Results] There is only 1.1.1.0 route in the routing table on R2 . Used to determine the link layer address of a neighbor, also used for DAD, etc. Ipv6 enable Ipv6 unicast-routing interface fastEthernet 0/0 The dual-stack host on the IPv4 network first uses HTTP to access the tunnel server through IPv4 . The end user fills in the web page and obtains the IPv4 and IPv6 addresses from the tunnel server. Tunnel Tunnel interface Both ends are common IPv6 networks, using regular global IPv6 addresses. The result is unreasonable, because the message exceeds the MTU of the R2 Fa1/0 port when it is passed to R2 , so R2 sends back an ICMPv6 message with TYPE=2 ( packet too big ) to R1 . In this back to R1 in the ICMPv6 message includes the allowed the MTU = 1400 , to inform the 2 : Reponse message, send all or part of its routing information, in a Response message Y View the ipv6 address information of the network card , such as validity period, prefered lifetime, etc. ( ipconfig is also available) Interface FastEthernet0/0 The arrival ISATAP the loopback of IPv6 packets, on a quilt ISATAP of IPv4 tunnel header, and then passed ISATAP 1000 – 1FFF Ipv6 address 2002::1/64 ipv6 enable No bgp default ipv4-unicast bgp log-neighbor-changes Router ospf 100 The configuration of R2 is as follows: But what if the A route is an OSPF external route? R1 The default load balancing method is destination-based load balancing. CEF 's destination-based load balancing is actually implemented by HASHing the destination and source IP addresses . In contrast, in fast forwarding, load balancing based on destination address is performed strictly according to the destination IP address.
