The current network is routed via EIGRP, but also has a lot of vlan's trunked everywhere...its an STP nightmare with various ISP's providing service via fiber, and a host of wireless bridges, that are any where from 10-40 miles.... My though was to use tunnel's and vrf-lite instead of trunking vlan's everywhere, but from what I am hearing, GRE tunnels are not going to perform. I have this working in a test network and it's working well. Other than I have not tried a performance test.
They do want separation on some of the networks, but not all. I have done this in the past with access lists and vlan's but its a pain. Is there any other way to segregate the traffic on routed network? Ideally they should have a router at each location and not a switch. Dan.
