Hello
My topology is as such
+----+ +----+
| R1 |-----------------| R2 |
+----+ +----+
| |
| |
+----+ +----+
| R4 |-----------------| R3 |
+----+ +----+
All the routers are running isis (level 2) and all the interfaces are configured with family inet6 addresses (including loopback interface)
The problem is with R2, while all the other routers have R2's inet6 loopback address (and the point-to-point addresses) on their isis databases and the inet6 routing table, R2 does not have any inet6 routes in the inet6 routing table except for the direct connected routes
paul@R2> show isis route inet6
IS-IS routing table Current version: L1: 0 L2: 1661
paul@R2> show route protocol isis table inet6.0
paul@R2>
IPv4 however works fine
paul@R2> show route protocol isis table inet.0 terse
inet.0: 16 destinations, 32 routes (16 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both
A V Destination P Prf Metric 1 Metric 2 Next hop AS path

When I check the isis database however the v6 prefixes are there
paul@R2> show isis adjacency

ge-1/0/1.0 R3 2 Up 18
paul@R2> show isis database R1 extensive | match "^[aA-zZ]+|v6"

I have confirmed all routers are using the same metric type (wide metric) what could be the issue?
