The figure above is the initial state.
IP address, and then take the destination IP address to look up in its own routing table. After finding the "best match" entry, the packet is forwarded according to the outbound interface or next hop IP indicated by the routing entry . This is the IP route. ( IP routing ) . And each router maintains a routing table locally.

Interface-level command to join a multicast group, that is, the interface becomes a member of the multicast group.
Ipv6 route 2002::/16 tunnel1
CISCO routers have two ways to find the global lookup of routes: classful ( Classful ) lookup mode and classless ( Classless ) lookup mode.
RIP and IGRP the passive-interface does not send routing updates, but to accept routing updates
The BGP4+ configuration of R2 is as follows:
!! Since Fa0 / 0 connected to a router rather than the host, to reduce unnecessary ra of

How does the prefix announcement work?
Ip route 10.1.2.0 255.255.255.0 10.1.254.1
This RS message via IPv4 tunneling, the outer layer is the IPv4 header, source address ISATAP the IPv4 address 184.108.40.206 , the destination address is 220.127.116.11 , which is ISATAP of IPv4 addresses. The IPv4 header is wrapped with IPv6 packets. The source address is the ISATAP host.
The configured static network path is redistributed into OSPF . In this way, when the intranet user needs to access the Netcom resources, because of the details of the network access, go to OR1 . To access other resources, take the default route to OR2 .
IPv6 is enabled, link-local address is FE80::CE03:1AFF:FEC4:0 Global unicast address(es):

2002: CA65: 0C01 :: 1/48 , R3 empathy. The next step is actually the trick of static routing. At this time, the intranet has data to go to 2001:0002::/16

The MTU value found by IPv6 PMTUD is cached by the source node. With CISCO IOS , show ipv6 mtu can be used to display the destination PMTUD value of each cache.
Route-map nat2 permit 10 match ip address 1
The configuration on R3 is as follows:
Interface Serial0/0 ipv6 enable
100x xxxx xxxx xxxx
This comprehensive thinking question helps you sort through several solutions:
Via FE80::FFFF:FE10:2, Serial0/0
Border Gateway Protocol (BGP) Connected
R2 ignores R1 update sent over, because the "active examination", from R1 sent from the RIP updates and R2 of S0 / 0 Kou not in the same subnet, so R2 ignored R1 incoming routing updates. At this time, just validate-update-source under the RIP process of R2 .

The PC does not need to receive redundant RIPng multicast messages.

The implementation of diversified strategies at the level has been able to achieve very good path control effects, and it is a very scientific and highly recommended method to control the flow of data by controlling routing. In addition to this, there are many, such as:
After the above configuration, A can initiate access to B , and uses the destination address 2001: 2 :: 2 to access B
After the PC , the PC regards the Router as a gateway, this lifetime
Ipv6 enable interface Serial0/1
The command distribute-list out works only on the routes being redistributed by the Autonomous System Boundary Routers (ASBRs) into OSPF. It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes.

by. So, R1 , R3 two under 6to4 visit each island, the solutions we have already spoken, but the R1 or R3 If you need to access non- 6to4 of IPv6 network do? R2 is needed , and R2 is a 6to4 relay router at this time . At the moment, R2 through one of its own IPv4 public network the IP , to give a 6to4 of IPv6 global unicast address polymerizable, the IPv6 address is used to respond to other 6to4 router tunnel establishment request.
