We are deploying 5 UC500s - 2 UC560, 3 UC540W in 5 different locations. Each of these locations will have a direct internet access via the WAN port of the UC500 as well as a MPLS router on the LAN to route traffic destined for the 4 other branches. We would like to send the intersite voice across the MPLS as we are able to use QOS and it is a seperate circuit and without internet traffic whatsoever.
What we are trying to accomplish:
UC500---->WAN PORT---->DIA---->internet only
UC500---->LAN/EXP(OR SWITCH) PORT---->MPLS ROUTER---->other branches and voice traffic
Obviously using routing statements to specify that x network is directed to MPLS router on the LAN and 0.0.0.0 is routed to internet gateway on wan port.
We do not want to use internet as some sites also have very small internet bandwith (512k-1mb) while the MPLS pipe is considerably bigger and as I had mentioned before - prioritized for this voice traffic.
