IPv6 IS-IS configuration examples
IPv6 IS-IS basic configuration example
Network requirements
As shown in Figure 115 , Router A, Router B, Router C and Router D, all enabled with IPv6, reside in the
same autonomous system. Configure IPv6 IS-IS on the routers to make them reachable to each other.
Router A and Router B are Level-1 routers, Router D is a Level-2 router, and Router C is a Level-1-2 router.
Router A, Router B, and Router C belong to area 10, and Router D is in area 20.

Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown)
2. Configure IPv6 IS-IS:
# Configure Router A.
system-view
[RouterA] isis 1
[RouterA-isis-1] is-level level-1
[RouterA-isis-1] network-entity 10.0000.0000.0001.00
[RouterA-isis-1] ipv6 enable
[RouterA-isis-1] quit
[RouterA] interface POS 2/1/1
[RouterA-POS2/1/1] isis ipv6 enable 1
[RouterA-POS2/1/1] quit
# Configure Router B.
system-view
[RouterB] isis 1
[RouterB-isis-1] is-level level-1
[RouterB-isis-1] network-entity 10.0000.0000.0002.00
[RouterB-isis-1] ipv6 enable
[RouterB-isis-1] quit
[RouterB] interface POS 2/1/1
[RouterB-POS2/1/1] isis ipv6 enable 1
