Routing strategy needs (reliability, redundancy, offloading model, etc.) R2#show ipv6 interface f1/0 FastEthernet1/0 is up,best ccna practice exams, line protocol is up The following is an example of an NA message: Internal BGP Image Set ip next-hop verify-availability 10.1.1.2 10 track 1 Router ospf 100 X By default , Cisco routers enable fast switching or optimal switching or cef switching instead of process After the configuration is complete, the BGP connection between R2 and R3 can simultaneously deliver IPv4 and IPv6 route prefixes. RIP-1 compatibility RIPv2 sends updates in the form of broadcasts, enabling V1 to receive S Image RIP database Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS Y If no conflict is detected after 1S , A will send a non-solicited advertisement (an NA message), announcing that I will officially use this IPv6 address. Image Transition from the old routing protocol to the new routing protocol Ipv6 route 2002::/16 tunnel1 !! When accessing the remote 6to4 network locally , take the tunnel !

Image 1 : Request message, requesting all or part of the routing information from the neighbor; RFC1058 Interface loopback 0 Next, we enter on the ISATAP host in CMD mode: Experimental needs Modified OSPF the AD value Interface FastEthernet1/0 Nexthop ::FFFF:4.4.4.4 ! Virtual-Template Virtual Template interface Virtual-TokenRing Virtual TokenRing F800 – FBFF Per packet load-sharing is disabled IP unicast RPF check is disabled Inbound access list is not set Outbound access list is not set 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. Image 32 bits It can contain up to 25 routing entries. Port number 179 Interface serial0/0 Neighbor FE80::CE02:8FF:FED8:0 activate Address-family ipv6 neighbor 4.4.4.4 activate Between routers, routing information is passed, and the distribution list has absolute control over routing information. Therefore, if it is in the direction, by deploying the distribution list, the specific route can be filtered, so that the local routing routing table of the distribution list is changed, and when the local router updates the routing information to the downstream router, the actually updated content is An entry that is affected by the distribution list.
