Cisco Bug: CSCuj29579 - CRS MC Bundle reporting multicast traffic loss after migration on 4.2.4
May 13, 2018
- Cisco Carrier Routing System
Known Affected Releases
Symptom: Multicast not enabled on Bundle-Ether60 on LC 1/x/cpu0. This causes complete multicast traffic drop on bundle-ether. The trigger was bundle IP address removal during Maintenance Window for link migration. Conditions: ipv4_mfwd_partner process on RP didn't send BE IM state/IP address because interface type was not set as bundle. This issue will not be seen every time, multicast bundle configs come from 2 paths i.e sysdb and GSP. If it comes from GSP first then things are fine but if it comes from sysdb then we hit this issue.
