- Cisco Carrier Routing System
Known Affected Releases
5.1.2.BASE 5.1.2.LC 5.1.3.BASE
Symptom: When IGP paths are changing, it is not updating RLDI of VPN leafs. This causes VPN leafs to keep pointing to stale pointers. Conditions: 1. The bwalk reason is not handled properly in shldi processing in HAL. 2. The bwalk Spec in SSE engine ends at leaf. This causes reason to not trickle down to child i.e. RLDI of VPN leafs. 3. In 2->1 case, SSE engine code is not setting bwalk reason to repair RLDI of VPN chains.
