I've a need to add a vlan to an existing network, and I'm having some difficulty going at it the "best" way. Allow me to paint a picture of the existing setup.
Firewall to the external world is an ISA 2006 appliance.
Internally at site A we have three switches, the ProCurve 2810-24, and two ProCurve 26-10-48's. Site A also has an MPLS router to connect to Site B. All web traffic goes through Site A.
Site A's internal addressing is 192.168.1.x
Site B's internal addressing is 192.168.2.x
What I hope to accomplish is to create a vlan for our voip phones so that I can build some QoS into the routers.
Here are some of the issues I've run into.
I've found that the ProCurve switches can act as routers. However, I have three of these switches, and the vlan ip configured on each switch should be different, correct?
- vlan 1 (main) - ip 192.168.1.3 (since 1.1 is the isa firewall and 1.2 is our mpls router)
- vlan 2 (voip) - ip 192.168.10.1
- vlan 1 (main) - ip 192.168.1.4
- vlan 2 (voip) - ip 192.168.10.2
-vlan 1 (main) - ip 192.168.1.5
-vlan 2 (voip) - ip 192.168.10.3
If this is true, how should the routing be configured so that traffic can reach the 10.x network?
Second, since I need to establish some QoS on both the mpls router and the external routers, these two routers also need some routing information to be able to find those networks. So where should the gateway for those networks exist?
I have a feeling that in the course of reading up on what vlan's are and how they're implemented, I may have made the problem more complicated than it needs to be. Hopefully someone can give me some clarity. Also, since I didn't give much detail above, I'm happy to give a little more detail or answer other questions in search of answers.
