• CSCuh18073
Symptom: In a domain with 2 BGP exit points acting in Active or Repair mode, traffic would be
exiting the domain through Repair path BGP PE instead of exiting through Active path BGP PE.
Conditions: This issue occurs in the following conditions:
–
Environment has 2 BGP exit points
–
A change in one of the core links to the primary BGP exit point results in Repair BGP PE
becoming Active BGP PE and vice versa
In this scenario, even after BGP convergence, data packets would traverse through previous primary
BGP PE(now repair path PE).
Workaround: There is no workaround.
