IPv6 IS-IS configuration examples
IPv6 IS-IS basic configuration example
Network requirements
As shown in Figure 104, 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 so that they can reach 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.
<RouterA> system-view
[RouterA] ipv6
[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 serial 2/2/0
[RouterA-Serial2/2/0] isis ipv6 enable 1
[RouterA-Serial2/2/0] quit
# Configure Router B.
<RouterB> system-view
[RouterB] ipv6
[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
