Redundant switch advice

[hobo28]

Hi all

First post so please be gentle.

I have been asked to design a network to link a satellite office to our main office. The WAN link will be redundant and the service provider will install 2 routers in case of HW failure.

I just want to connect them straight onto a couple of 4506's but having never done anything very complex before, how do I configure the two switches so that they will be able to support the redundant routers. The idea is that each switch will have one in each.

I guess the question do you have access to the routers ? If not you really don't have a lot of options . If you owned the routers you could setup HSRP and point the switch gateway at the virtual default gateway of the router hsrp setup and set hsrp to track the serial interfaces so if one side goes down it automatically flop to the other side . Otherwise I'm not sure if you don't have control of the routers .

I can ask the WAN provider to pretty much do what we want.

So would I need to configure the routers on the same VLAN?
