IPv6 deployment is expanding rapidly in transport networks. In this context, interoperable PCEP session establishment and operation over IPv6 transport is a key requirement. This test verified full PCEP operation over IPv6-only transport, without IPv4 fallback.
For each run, we first configured IPv6 connectivity between the PCE and PCC peers and verified reachability. We then successfully established PCEP sessions using IPv6 source and destination addresses. All implementations operated stably with no connectivity issues.
