Re: vlan routing issue

DOn't take this the wrong way, but that is a truly horrible design.

 

You have 3 routers on VLAN1 AND a whole load of access-layer devices.

Your switches have IP routing enabled but don't have default routes.

 

I would go back to the drawing board - you need to decide:

 - Does your router perform your "Core" inter-VLAN routing functions

OR

 - Is your router only an "Edge" device.

 

Personally, I would use Switch A as the "Core":

 - Home all VLANs on Switch A.

 - disable routing on all other switches.

 - Remove VLAN 1 address from router

 - create point-to-point link between Switch A & Router

 - put default route on Switch A pointing at router

 

Even better, get two layers switches, l,ink them both to the router, enable VRRP and have some "Core" redundancy that way.
