Known Affected Releases

6.0

Description (partial)

Symptom:
When using loose hops to the L1/L2 routers with dynamic to fill in those gaps on both ends.  I've seen this same issue when my LSP's are within the same ISIS area and just using completely dynamic LSP's and when I'm crossing L1/L2 boundaries like in this case.

Conditions:
