Known Affected Releases

5.1.2.BASE 5.1.2.MPLS

Description (partial)

Symptom:
This can happen in a router where we have MSC-X cards along with MSC-140/MSC-40. If P2MP tunnels (P2MP-TE or P2MP based mLDP profiles) are configured on MSC-140/40 cards, we may see a fib_mgr assert on MSC-X card.

Conditions:
P2MP tunnels (P2MP-TE or P2MP based mLDP profiles) configured in MSC-140/40 cards in a router that has MSC-x also installed. Some of the P2MP messages are propgated to all line cards in the router. The MSC-X card installed in this router will also receive this message. Since we do not have complete support  for such message processing, we may run in to issues in fib_mgr process.
