    Hello friends

    Facing a typical problem with SDH protected circuits in revertive mode
    connected to Cisco GSR routers on both ends.

    When the primary link of the protected circuit goes down, alarms are
    received at both end GSRs, one receives a PAIS & other receives a PRDI.
    So interface goes down at both end routers.

    However when primary link comes back up again and circuit reverts from
    secondary to primary, PRDI alarm is received at one end and interface
    goes down. However, other end router does not receive any alarm & the
    interface stays up.

    First hop mux connected to GSRs are Tejas Mux

    Any thoughts on this issue ??
