IPv6 IS-IS configuration examples
IPv6 IS-IS basic configuration example
Network requirements
As shown in Figure 97, Switch A, Switch B, Switch C, and Switch D, all enabled with IPv6, reside in
the same AS. Configure IPv6 IS-IS on the switches so that they can reach each other.
Switch A and Switch B are Level-1 switches, Switch D is a Level-2 switch, and Switch C is a
Level-1-2 switch.

Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure IPv6 IS-IS:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] isis 1
[SwitchA-isis-1] is-level level-1
[SwitchA-isis-1] network-entity 10.0000.0000.0001.00
[SwitchA-isis-1] ipv6 enable
