I've got a site thats split into two areas by two routers that connect a LES link between both sites. Site 1 has vlan 250 and site 2 has vlan 251.
I'd like to implement RSPAN to mirror each vlan to a destination port on the switch with ip 10.4.1.2 to port fastethernet 0/23. This switch is in site 1. My question is how can I configure RSPAN to allow traffic from site 2 to reach switch 1's port in site 1?
