I have a microwave link between two buildings. The microwave link has two antennas at each location in effect giving me two layer 2 connections between locations.
My questions is, I would like to aggregation these two links into one layer 3 link with an IP on each side. What would be the best way to do this and with what equipment?
Was thinking but have never tried to create a port-channel group with 2 FE interfaces on say a 3560 then create a GRE tunnel with source interface of the port-channel. Don't know if that would work, but certainly seems like a viable solution. I would like the option of doing IPSec over this connection too though and don't think the switch would be a good option then.
Any thoughts would be appreciated.
