Cisco Bug: CSCul73951 - 511 UI: inconsistent process state between the RSPs upon config removal
Aug 01, 2018
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Symptom: If HSRP or VRRP are configured on a dual-RP IOS-XR system, the HSRP/VRRP process will be started on both the active RP and standby RP. As HSRP/VRRP use a warm-standby HA model, the HSRP/VRRP process on the standby RPs will be blocked during initialisation by the sysmgr process. If the HSRP/VRRP configuration is then deleted on the active RP, the HSRP/VRRP process on the active RP will terminate. However the HSRP/VRRP process on the standby RP will still be blocked by the sysmgr process. If a RP failover then occurs, the blocked HSRP./VRRP process will be allowed to run by the sysmgr process and will enter their main event processing loop, where there will be nothing to do because there is no HSRP/VRRP configuration. The HSRP/VRRP process on the newly active RP (after RP failover) will continue to run. Conditions: Only occurs on dual-RP IOS-XR systems, after the HSRP/VRRP configuration has been deleted and there has subsequently been an RP failover.
