Known Affected Releases
Symptom: The following error may be seen on a IOS-XR router running 4.0.1 after a RP failover: tunl_gre_ma: %HA-CHKPT_MESSAGING-7-STANDBY_OPEN_TIMEOUT Conditions: This is a rare condition that is seen after the following events 1. Configure GRE tunnel(s) 2. Delete all GRE tunnels 3. Perform an RP Switch over,. The tunnel MA on new active RP failed to sync with tunnel MA on standby RP for checkpoint record sync because tunnel MA on standby RP will not be spawned due to no tunnel configuration. This bug has no functional impact. Instead it just results in the syslog message after the RP failover. The fix for this is that when the standby RP goes active it will check if tunnels are configure and if not it exits gracefully.
