VLANS across a WAN-Newbie

[angel-moon]

All,

in a situation where there are 2 2811 routers connected by a point to point I need to configure a Voice and Data VLAN on some adtran switches.  Can someonepoint me in the right direction for what I need to do on each router to pass the VLAN traffic?  Very Newbie quiestion I know.

All replies rated.  Thanks in advance!

Hi Angel,

You don't need to extend the vlans from each location over the WAN circuit.  Keep your voice and data vlans local to the site.  Use each 2811 as  a default gateway for your local vlans, and then use /30 for your WAN link

site-A-local-vlan-----2811----------WAN /30--------2811---------site-B-local-vlan

Thanks.  On an even more basic level is there anything I have to do  on the router other than have the router be the default gateway for the VLAN?

Hi,

you must have routes  for the VLAN subnet not directly connected either via static routes or routing protocol.

You will need to configure one or more interfaces for your local vlans

example

interface fastethernet 0/0

ip address 10.10.10.1 255.255.255.0

then you need to configre your WAN interface

interface x.x

ip add 192.168.1.1 255.255.255.252

Do the same for the other location with different IP segment on the lan and the same segment on the WAN

then you need to run a dynamic routing protocol or use static routes to do the routing

If it is a small network static routes are good enough
