Cisco Bug: CSCuq80839 - Standby SUP keeps reloading due to Bulk-sync failure due to PRC mismatch
Apr 22, 2020
- Cisco 7600 Series Routers
Known Affected Releases
Symptom: On a dual-RP system with one or more xconnects configured, the standby RP may repeatedly reload due to Bulk-sync failure caused by PRC mismatch. The output of the exec command <CmdBold>show redundancy config-sync failures prc<noCmdBold> displays errors like the following: interface TenGigabitEthernet1<interface number> ! <submode> "interface" - xconnect <IP address> <VC ID> encapsulation mpls ! </submode> "interface" Conditions: This symptom has been observed on routers running Cisco IOS Release 15.2(4)S (all versions). The trigger for this issue is reconfiguring a xconnect with a new peer address and/or VC ID on an interface that already has a xconnect configured without first unconfiguring the existing xconnect and then performing a switchover to the standby RP.
