Bug Id: | CSCuq19149 | Title: | mVPN - ME3800 acting as 'P' router is causing PIM adj to drop b/w PE's |
|
Status: | Fixed |
|
Severity: | 2 Severe |
Description: | Symptom:
mVPN setup, ME3800 acting as P router flushes S,G entry.
The S,G on an 'P' router maintains the pim adjacency for the hello packets exchanged on the default mdt. Although continuous pim hello's are seen on 'P' router sent from the PE routers, but still the mroute output displays the S,G entry being deleted and re-created, thereby causing PIM adjacency to go DOWN between the PE's.
AND/OR
If the mVPN setup comprises of an PRIMARY PE which is sending mcast traffic regularly and an BACKUP PE which is passive and only takes over when PRIMARY is DOWN, it was noticed that the BACKUP PE's S,G on 'P' router was getting flushed.
Conditions:
mVPN setup with ME3800 deployed as 'P' router.
Workaround:
none
