Bit of advice if possible.
I've got a project to implement VLAN's on a MAN, which is easy enough, using CAT4506 and a mixture of 3750 and 2950 switches. The Vlan aspect is OK but I'm a bit unsure as to how to integrate the WAN into the design.
I have two core WAN access sites each with 2 * cat4506 switches of which one at each site attach to a WAN router (3725)
The CAT4506 switches will be doing the vlan routing but the 3725 routers (one at each site in a HSRP group) will be routing the WAN. Obviously these need to be attached to the catalysts for WAN access. As I have seperate routers for vlan routing and wan routing, what is the best way to configure this ?????
Is configuring a seperate VLAN for the routers the best idea ? or is it best to use the sub interface option on the router ethernet ports ?
Do I just use a static route of last resort on the Catalyst pointing to the routers ?
