Symptom
A CPLD upgrade may be required in cases in situations where a keepalive timeout may be observed. Such notable issues are documented under CSCvg29615/CSCvd82858.
Conditions
This is applicable for ASR1000 routers with an RP3. Any RP3 without a CPLD version of 17042115 from 'show platform' may potentially be vulnerable to CSCvg29615/CSCvd82858. Here is what expected to be seen with the CPLD update from show platform:
