ZXR10 ZSR V2 Configuration Guide (IPv6)
Run the
show isis ipv6 topology
command to check whether the topology is correctly
computed (For the single-topology environment, run the
show isis topology
command
instead to check it). If the topology has been successfully computed, the execution results
will indicate the following item. If the metric is “–”, it indicates the local router. If the metric
is “xx”, it indicates that the destination is unreachable.

Run the
show isis circuits
command to check the interface information and Designate IS
(
) election. If the interface status is "UP", the interface is normal. If the interface status
is "DOWN", the interface is abnormal. Then it is necessary to check the link status. The
Level1-DR item shows the system-id of the DIS.

Run the
show ipv6 forwarding route isis-l1
or
show ipv6 forwarding route isis-l2
command
to check route advertisement. If route advertisement is normal, the route advertised by the
loopback interface of the peer router can be seen.

If neighbor establishment and route advertisement are normal, the loopback interface of
the peer route can be pinged successfully.
