!! activated RIP Router isis ! Ip sla monitor 1 The router uses the ICMPv6 redirect message ( ICMP TYPE 137 ) to inform the nodes on the link that there is a better router for forwarding packets on the link. The node that receives this ICMPv6 redirect message can modify its local routing table based on the new router address in the redirect message. Basically up from the mechanism with IPv4 in ICMP redirect no different. 1 Technical overview 0xF895 R4#sh ip ro 192.168.1.0 Ipv6 unicast-routing ipv6 cef IPV6 and subnetting 200 Address-family ipv4 Link-local address (Link-local address) As OSPF2 create a route in the static summary routes ( the Null0 ), and static routes redistributed into OSPF1 modified OSPF1 administrative distance, the OSPF1 priority than OSPF2 administrative distance OE2 2004:1:2::/64 [110/20] External route tag Router(config-router)# default-information originate [route-map x] Must be zero Global command, enable IPv6 multicast-routing . After the switch is enabled, all IPv6- enabled interfaces automatically open IPv6 PIM. The tunnel interface is used for ISATAP . In this case, the tunnel interface generates a 64-bit interface identifier based on the IPv4 address . This interface identifier matches the upper-level fe80:: to form the Linklocal address of the tunnel interface : fe80:: 0000:5efe:202:202 . In addition, you need to configure a global unicast IPv6 address for the ISATAP tunnel interface . You can configure it manually or by prefix +EUI64 . Here,cisco ccna study guide, EUI-64 is the special 64bits interface identifier described above .
