Multiple Static Routes
Posted on 2014-10-28
I am trying to implement VoIP with SIP trunks on my network. I have a campus environment with three campuses and one centralized CORE Switch (Cisco 4510) in the data center at the main campus.
On the Cisco 4510 I have a voice vlan and vlan interface for the voice network at each campus. At the remote campuses I have Cisco 3750 as the distribution switch and Cisco 3560 as the access layer switch. The Cisco 3750 has a trunk to the Cisco 4510 allowing ALL vlans across an I have another trunk from the Cisco 3750 to the Cisco 3560 allowing ALL vlans.
The problem I am facing is there are SIP trunks at each campus that connects to the Providers MPLS network. Each campus is to send voice traffic to their local SIP trunk, not across the WAN. On the Cisco 4510, there is a static route to the providers network (10.250.0.0). Since ALL the voice vlans and vlan interfaces reside on the Cisco 4510, how do I send the voice traffic across the local SIP trunk at each campus?
Can I have multiple static routes to the providers network?
Do I have to create the vlans and vlan interfaces on the Cisco 3750 and 3560 at each campus?
