Hope you can help with this one or certainly point me in the right direction.
- We have two MPLS circuits managed by two different suppliers, one carries VOICE the other DATA
- We are to decommision the VOICE MPLS and have increased the bandwith of the DATA MPLS to carry VoIP traffic too.
- At both of our sites A & B ,devices connected to the LAN have a default gateway of the VOICE providers Cisco 2600 router , which then goes into the LAN switching. (see diagram)
- So what I am trying to achieve is toto simply replace these 2600 routers from the VOICE MPLS provider with our own so we dont have to change the default gateways at both sites.
- Our Cisco 2600 routes are plugged into each LAN switching environment with two subinterfaces configured, one for voip and the other for data
- The problem is from the router and respective subinterfaces we can get to the other sites destination without any issue, but if for example a user is at site A with Ip address 10.16.11.12/16 they cant ping the VOIP subnet at site B 10.3.11.0/24. But If a ping is issue from the Site A test router then the 10.3.11.0/24 subnet is reachable but only on the 10.3.12.0/24 configured subinterface.
- So i guess what Im saying is 10.16.0.0/16 from the LAN needs to be able to get to 10.3.11.0/24
- Note at site A 10.16.0.0/16 & 10.3.12.0/24 can communicate no problem and at site B 10.207.0.0/16 & 10.3.11.0/24 can communicate no problem.
- We are using IP routing, should we be using route-maps?
Hope that makes sense!
many Thanks in advance
Please see attached configs and test network diagram
I have this problem too.
