Solved: Cisco Switch routing to Voice VLAN to different router. Help!

efowler · ‎05-22-2023

Hello all, currently I have a Cisco Switch that is routing all VLAN 10 (Voice) traffice to a different router. We are wanting to get ride of that router (ASA 5505) and want all the VLAN 10 traffic to go out the same location as the VLAN1 (data) router. Our phones that use this VLAN are on a different subnet (192.168.16.x) and use the gateway 192.168.16.1. Here is the show run from the cisco switch.

My guess is to remove the switchport access and voice VLAN on port 1/0/24? Will that stop the routing of the VLAN 10 traffic to that port? And then by default just route VLAN 10 to the F380 like the data traffic?

I have already created a static route on my router (F380) for the 16 subnet.

this make phone have GW is SVI VLAN 10 in SW and then the traffic will forward to Barracuda

can you draw the topology

I added a picture that may help!

if you want to delete the connect for VLAN10 in ASA

I changed the

default gateway

and had to activate the network in barracuda. All works now thanks again!

Hi

Do you have any IP address on the network 192.168.16.0 on the ASA side? If you do and you want to move the network to Brocade you need to remove. Direct connected network will have preference.
