Image ! Interface FastEthernet0/1 vrf forwarding cisco ipv6 enable This can indeed avoid the suboptimal path problem, but it leaves a hidden danger: Ipv6 unicast-routing Fa0/0 This is not much to say? For PBR , when creating a route-map , it is all permit . Frame-relay map ipv6 2000:12::2 102 broadcast 100.1.1.0/24 . At the same time, this re-release becomes the summary route of OSPF . Even if two ASBRs are returned , because there is a static summary route locally, the summary route of OSPF is directly ignored , and sub-optimal is not generated. Path, this route will not be re-released back to RIP and cause other problems. V1 uses broadcast, which is sent every 30s by default , using UDP port 520 (source, destination port) B removes the IPv4 header of the packet , obtains the original IPv6 data, and forwards it to PC2 .

Next Hop Therefore, from here we can see that the route summary is a risk of looping. One way to solve the above problem is to add a static route on the Layer 3 switch: ip route 192.168.0.0 255.255.0.0 null 0 , this way, when it receives access DAD [Experiment 2 ] There are subnet routes (match); there are default routes, subnet routes OSPF and RIP PE1#show bgp vpnv6 unicast all labels Ip address 10.1.12.1 255.255.255.0 The IPv6 address that the node must have : The forwarding entry is only (and the outgoing interface list is empty) and will not be processed further. These multicast data are then discarded at R2 . Experimental example: Called when republishing Destination address: The address of the host or network. [Two times of prefix] Source starts to send IPv6 packets using MTU=1300 , and the packets reach the destination smoothly.

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.
