Table 9-28. IPv6 Default Gateway CLI Commands (Continued) CLI Command show ipv6 route Description Displays the current state of the IPv6 routing table. The following are examples of these CLI command: console(config)# ipv6 default-gateway fe80::abcd console(config-if)# do show ipv6 route Codes: L - Local, S - Static, I - ICMP, ND - Router Advertisement The number in the brackets is the metric. L 3000::/64 is directly connected, VLAN 20 Lifetime Infinite L 4003::/64 is directly connected, VLAN 20 Lifetime Infinite L 5003::/64 is directly connected, VLAN 20 Lifetime Infinite L 6003::/64 is directly connected, VLAN 20 Lifetime Infinite ISATAP Tunnel To deliver IPv6 addresses in an IPv4 network, a tunneling process must be defined that encapsulates IPv6 packets in IPv4 packets. The Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is an IPv6 transition mechanism that is used to transmit IPv6 packets between dual-stack nodes (nodes that can accept both IPv4 and IPv6 addresses) on top of an IPv4 network. When enabling ISATAP on a tunnel interface, an explicit IPv4 address is configured as the tunnel source, or an automatic mode exists, where the lowest IPv4 address is assigned to an IP interface. This source IPv4 address is used for setting the tunnel interface identifier according to ISATAP addressing conventions. When a tunnel interface is enabled for ISATAP, the tunnel source must be set for the interface in order for the interface to become 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 IPv4 address. Thus, a Link Local address will be represented as FE80::5EFE:w.x.y.z 222 Dell PowerConnect 55xx Systems User Guide
