IPCC Resiliency issue - Dummy PG Setup

Unanswered Question

Hi All,

We have IPCC 7.0 (SR4) geographically distributed setup for resiliency.  The Rogger, Agent PG, IP IVR, CCM are distributed across 2 different sites.

Currently there are 2 PG's (PG1 - CCM & IP IVR PIM's, PG2 - MRPG) installed in the Agent PG Servers at both sites. The MR PG is currently out of Service and we are not in a position to start the service currently, but we do not want to remove it either.

Since PG2 is not in service, we are facing problem that the Router failover (to Router B) does not work. We understand from previous postings that installing Dummy PG is the solution to resolve the IPCC resiliency issue.

The question is ...is there a limitation from Cisco that the maximum number of PG's which can installed per server is 2..?.Can we install the 3rd PG on the same physical server (Agent PG),  since we have the MR PG out of Service, we can install and start the 3rd PG ( Dummy PG) which we believe will resolve the resiliency issue. Will Cisco come back saying that this is an un-supported configuration..?.

We have busy call routers and other  servers in the setup and hence any other systems in the current setup cannot be considered for Dummy PG installation.

Appreciate your suggestions in this regard.

Have you considered disabling the PIM on PG2 and starting it so that it connects to the router so you have 2 PG's connected?  Then when you are ready just enable the PIM on PG2.  This would save installing a 3rd dummy PG.

Whether you can have 3 PG's or not on a server will depend on the specification of the hardware. A dummy PG would not take up much processor or memory as it would not have a PIM enabled.
