We have our remote branches set up in a 16 bit mask configuration.
I would like to move this over to 24 bit and isolate everything in seperate VLANs.
We have Cisco VoIP for each branch with Call Manager in the Main site branch.
Currently the switch is configured with all devices in VLAN1
The workstations that have phones are configured with voice vlan 2 and get an IP address from the scope configured on the router:
ip dhcp excluded-address 10.254.12.0 10.244.255.255
ip dhcp excluded-address 10.254.0.0 10.244.12.0
ip dhcp pool VOICE-DHCP
network 10.244.0.0 255.255.0.0
Both of these vlans have a subinterface on the router, both are 16 bit.
There is a trunk configured from the router to the switch trunking only these two vlans.
description DATA VLAN
encapsulation dot1Q 1 native
ip address 10.10.10.1 255.255.0.0
description VOICE VLAN
encapsulation dot1Q 2
ip address 10.254.10.1 255.255.0.0
h323-gateway voip bind srcaddr 10.254.10.1
I would like to create vlans on the switch
SVIs and device all devices into different vlans:
My question is regarding making the routed connection from the SVIs to the router.
I am thinking I can leave the voice config in a 16 bit mask.
But, if I have SVIs created on the 3560 switch, how can I route the vlans up to the router?
Would I create a vlan for the router interface and uplink the switch to the router (I would need routes from the SVI interfaces to the router interface)?
Or would I need to add subinterfaces for each one of the SVIs and trunk them up to the router?
