Next on R4 , summarize the external routes that are re-released by itself: Dynamic NAT-PT On CISCO IOS , the default valid time is 30 days ( 2,592 000s ) and the prefer time is 7 days ( 604 800s ).

The interface must be in the in/out direction. The interface is optional. If no interface is configured, the interface takes effect. Originally, the IPv4 prefix of 3.3.3.0/24 passed by R3 , NH is 254.128.0.0 , which is a reserved address. This address is of course illegal, so R2 ignores this route directly. Solution, may be R3 to the R2 do out direction route-Map , and provided IPv4 prefix NH2 , such as: If you want to turn off ICMP redirects, you need to use no ip redirects on the interface .

OSPFv3 ( RFC2740 ) Field name 2002 : IPv4 address : Subnet ID : The IPv4 address above the interface ID is the public network IPv4 address obtained by A or B. Note that this public network IP is very important. This public network IP change may lead to IPv6. Intranet IPv6 had to be readdressed. And, of course, this IPv4 address cannot use a private IPv4 address. ! Image !

Otherwise this 6to4 relay using the anycast prefix is unreachable in the IPv4 Internet. ipv6 rip RIPprocess enable !! activates the RIP Interface fast1 / 0 Image Router ospf 1 Address-family vpnv6 Routing strategy needs (reliability, redundancy, offloading model, etc.) Verify again, instead of detailed routing, use a summary route of ip route 10.0.0.0 255.0.0.0 , the next hop is R3 , the effect is the same as above, also take R3 . Therefore, as long as it is not the default route, as long as there is such a matching route in the routing table, the route is taken preferentially, and the route-map is taken without the route . OR2 configuration Certification No bgp default ipv4-unicast neighbor 2001::1 remote-as 12 Configure OSPF unicast updates: Access-list 1 permit 11.11.11.0 Pop tag If there is a class route lookup ( no ip classless and ip cef is off ), when receiving a data packet, the router first searches for the main class to which the destination address belongs. If there is a main class route in the routing table, then the subnet is searched. If there is a subnet route, the query is limited to these subnets and further searched. If the final lookup fails (no subnet matches this route), the packet is dropped even if there is a default route; if there is no local For the main class route, see if there is a default route. If there is, then it will be forwarded by default route. If not, the packet will be discarded.
