[cisco-voip] Why Do Route Lists Unregister?

[Keith Klevenski]

Hi all,

 

I asked this question recently, but I never got a solid answer.  

 

A few minutes ago we had an issue between our two core 6500's and sw1
was not accessible, but sw2 was (an rspan gone bad).  Each switch has a
6608 with several PRIs off each one in each switch.  The publisher is
off sw1 and the subscriber is off sw2.  After the rspan was removed from
sw1 (console access via Envoy) traffic starting flowing normally again.
Several minutes later I was informed that no outbound calls could be
made.  I looked around and noticed that all route lists were
unregistered and of course no calls were going out.  I reset all the
route lists and they registered and calls started going out normally
again.  

 

So the question again is why would route lists unregister and stay
unregistered until they were all reset?  All of our route lists were
unregistered, even route lists that only contain one ICT or one gateway.
It seems related to CCM losing connectivity to the gateways in the route
lists, but why they would stay unregistered until a reset eludes me...

 

Any input appreciated as always!

Keith
