GSR POS interface issue with FRR

Jan 25, 2007 1 Replies

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 ??
