Multiple Routing Tables - Sup 720

darkbeatzz
Level 1
Level 1

Guys,

is this possible to do? If I want to have groups of vlans to have their own routing tables preventing the groups to route between eachother and push them to a default gateway of a firewall.

if so do you need any special hardware or software? Is an FWSM required?

Any good docs on this would be usefuly cant seem to find anything on it.

thanks

Hello Mick,

this is possible with sup720

you can use VRF lite or full featured MPLS VPN to have separate routing tables and subsets of interfaces

see

or

the difference is that in VRF lite no MPLS links are used and you need to provide dedicated logical links for each topology.

With MPLS this is not needed.

A FWSM is not required but it can completes the solution in some scenarios

Edit:

a design guide
