Hi - i have 2 x L2 WAN links between buildings.
1 = 1G wireless (seen by the switch as an L1 cable)
1 = 155Mb ISP (seen by switch as an L1 cable)
Right now they're set up in RSTP, but it would be great to utilize the very expensive 155Mb link no-just when the primary link is down.
L3 obviously easy, L2 challenging.
