So, quick post to help anyone else who runs into this problem in IOS-XR land.
While attempting to issue commands related to the BGP process on the box and I was meet with no response from the box. I was able to break the process with the typical Ctrl + C process, and issue commands to other processes on the box, but the BGP process just refused to response.
Reviewing the logs, I was able to find some errors related to no response being received from the BGP process :
RP/0/RSP0/CPU0:Apr 9 22:55:42.109 : sysdb_shared_nc: %SYSDB-SYSDB-6-TIMEOUT_EDM : EDM request for 'oper/ip-bgp/gl/act/shared/vrf/default/afi/' from 'bgp_show' (jid 65855, node 0/RSP0/CPU0). No response from 'bgp' (jid 1047, node 0/RSP0/CPU0) within the timeout period (100 seconds)
You can see that there is a ‘no response from ‘bgp” string in this log message. The quick and easy way to take care of a hung process like this is to restart it by issuing the following command :
RP/0/RSP0/CPU0: router#process restart 1047 location 0/RSP0/CPU0
WARNING : Issuing this command will rock the BGP process, so plan accordingly. You may experience a brief outage so schedule it during a typical maintenance window.
