I have two networks (net1 & net2) in one site (Site A) and two networks (net3 & net4) in another site (site B), I want to connect the two sites but by isolating the access so net1 can access net3, and net2 can access net4.
Leased line of 300Mbps will be used to connect the two sites, a backup link will provided as passive line in case of failure of the main line.
I read about VRF lite that can be used to make virtual tables. (example here http://packetlife.net/blog/2009/apr/30/intro-vrf-lite/)
I am thinking to install two 3750 in each site and connect each of the leased lines (main and backup) to each switch.
My question is does the catalyst 3750 support the VRF lite feature? And does the interface support the creation of subinterfaces of dot1q (like if I connected the service provide Giga link to the 3750 switch and create two dot1q sub interfaces each one with two different IP one for VRF-A and one for VRF-B)?
Or do u suggest any other solution?
A brief drawing is attached.
