This source IPv4 address isused for setting the tunnel interface identifier according to ISATAPaddressing conventions. When a tunnel interface is enabled for ISATAP, thetunnel source must be set for the interface in order for the interface tobecome active.An ISATAP address is represented using the [64-bit prefix]:0:5EFE:w.x.y.z,where 5EFE is the ISATAP identifier and w.x.y.z is a public or private IPv4address. Thus, a Link Local address will be represented as FE80::5EFE:w.x.y.zshow ipv6 route Displays the current state of the IPv6 routingtable.console(config)# ipv6 default-gateway fe80::abcdconsole(config-if)# do show ipv6 routeCodes: L - Local, S - Static, I - ICMP, ND - RouterAdvertisementThe number in the brackets is the metric.L 3000::/64 is directly connected, VLAN 20 Lifetime InfiniteL 4003::/64 is directly connected, VLAN 20 Lifetime InfiniteL 5003::/64 is directly connected, VLAN 20 Lifetime InfiniteL 6003::/64 is directly connected, VLAN 20 Lifetime InfiniteTable 9-28.
