NEXT_HOP : Indicates an IPv6 address, or an aggregatable global unicast address, or an aggregatable global unicast address and its next hop local link address. 4000 – 5FFF Ipv6 address FE80::FFFF:FE10:1 link-local tie. When B accesses the IPv6 network, the IPv6 address can be taken from the pool . In addition, in order to allow V4 network access V6 network has goals, but also made a static mapping, the 2001: 1 :: 1 mapped to 202.101.100.111 , so, B will be able to use 202.101.100.111 This IP to access IPv6 hosts A .

The new routing table is typically sent to neighboring routers on a regular basis, and the triggered update is sent immediately in response to changes in the routing table. An IPv6 packet consists of a basic header plus zero or more extension headers plus an upper layer protocol unit.

The solution is to configure static summary routes on the two ASBRs : This comprehensive thinking question helps you sort through several solutions: 4 0000 1xxx xxxx xxxx Router(config)# ipv6 route destination IPv6 network / prefix length { outbound interface | next hop IP } As defined in RFC2462 , plug and play utilizes RS and RA messages. !! Interface activates IPV6 IPv4 Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
