5300 routing

[rob misz]

Two procurve 5308 connected together on port c1. Switch A and Switch B are connected together on port c1. Switch A and Switch B are procurve 5308s. Also,these 5308 also have layer 2 switch connected to them on port c1.When i do a show ip route i see that vlan 1 is the vlan that the switches are learning there routes from. Do i need RIP enabled on every VLAN or can i just leave RIP enabled on VLAN 100 and have that VLAN be the vlan where the switch learns its routes from

If I understood you correctly...

You can do the RIP-stuff in only one of your VLANs, then the switches exchange routes through that VLAN.

Drawback might be (depending on your topology) that routing of the traffic will probably also take place over that VLAN, possibly causing more L3 hops than neccessary.

Thinking of it: I even suspect you are doing something unsupported if you want to have the switches form a RIP-partnership in every VLAN. After all, the goal of RIP is to exchange routes, and the routing-table is valid for the whole switch, not for just one VLAN.
