By adding the "ipv6" parameter to the command, the IPv6 IS-IS route information will be displayed:
show ipv6 route isis
The system output would look similar to the following:
Codes: (L1) internal level-1, (L2) internal level-2, (eL1) external level-1,
(eL2) external level-2 (S) summary, (IA) inter-area,
(E1) external type-1, (E2) external type-2, (I) internal,
(E) external

CLI Commands for ISIS
The following table lists many of the CLI commands that are used in configuring and managing both MT IPv4 (ID #0) and
MT IPv6 (ID #2) routing.
For more information on these CLI commands see Command Line Descriptions.
