Design help - 2 sites with Voice and data. Netvanta 1638P

[orbrit]

I'm taking over a project for a client - the network admin left abruptly.

They have purchased an IP phone system (Mitel) and also have 4 Netvanta 1638P switches, AOS R10.7.0(ActivChassis enabled)

The current network is 2 sites connected by 100 Mb fiber, with Cisco 2811 routers as gateways for each subnet

Site A:

192.168.10.0/24

Site B:

192.168.20.0/24

Proposed network:

Site A.

Data VLAN 10,192.168.10.0/24, VLAN Interface IP 192.168.10.254

Voice VLAN 11, 192.168.11.0/24 VLAN Interface IP 192.168.11.254

Site B.

Data VLAN 20,192.168.20.0/24, VLAN Interface IP 192.168.20.254

Voice VLAN 21, 192.168.21.0/24 VLAN Interface IP 192.168.21.254

Each site has 2 Netvanta 1638Ps, stacked with the Dual XIM modules

Phones in both sites need to connect to controllers on VLAN11 and 21

PCs and Servers in both sites need to connect to each other.

Each site has it's own Internet access and Cisco ASA firewall. 192.168.10.250 (site A) and 192.168.20.250 (site B)

Devices in Site A (both VLANs) need to also be able to access a third location connected via a router in Site B. (192.168.20.253)

I need help understanding how to connect the switch stacks between the sites - preferably without the Cisco routers.

My first idea was to put all 4 VLANs on both switch stacks, with all the VLAN interfaces on the Site A stack.

The problem I see with that is any traffic that has to be routed out of stack B has to first find the route from stack A.

How do I connect Stack A to Stack B and route between all the VLANs?

It appears you opened a ticket with ADTRAN Technical Support on this forum post.  When you get a chance, will you post the results?  It will be helpful for users with this question in the future.

I called Adtran support when we first got the switches and had questions about stacking and general design but didn't actually get help with specifics.

I figured out how to achieve what we needed though.

Here's the breakdown.

Site A: VLAN 10 Interface 192.168.10.254

Site A. VLAN 20 Interface 192.168.20.254

Trunk port (1/0/48) configured with VLAN 20 default

All other ports set to VLAN 10 default

Site B VLAN 20 Interface 192.168.20.252

Trunk port (1/0/48) configured with VLAN 20 default

So All switches are part of VLAN 20

Traffic from 192.168.10.0/24 to 192.168.20.0/24 is routed on the site A switch stack and sent over the trunk to Site B stack

Traffic from 192.168.20.0/24 to 192.168.10.0/24 is sent over the trunk and routed on the Site A stack

Traffic from 192.168.10.0/24 to 172.16.10.0/24 is routed to Site B stack (192.168.20.252) and to the other router at 192.168.20.253

So far so good.

No, thanks. It's all working as it should.
