Created DH Rings using Ports 4/1 in WRC and 5/1 in PRC ??? While WRC 4th card is ACTIVE & 5th card in PRC is Stand-by. ??? After REP is converged at both the ends completely, Deleted the PBR & Rings. ??? Checked in both WRC & PRC for REP deletion in IOS using Show REP Topology command, and made sure about the deletion. ??? After confirming Ring Deletion as mentioned above, reloaded 4th card in WRC. ??? Once 5th card in WRC came as Active, checked for the REP topology and found Partial Ring topology is available for WRC end. Workaround: Reload the standby PTF after deleting the ring.
