Consider the following setup.
Lab A with Switch SW1
Lab B with Switch SW2
Lab A and Lab B have an IPSec VPN tunnel over the internet (no mpls).
They have 2 cisco 2811's between which the ipsec tunnet is established.
Is it possible using some technology (Ethernet over IP ?) to have a "virtual cable" to connect
SW1 <------- virtual ethernet ---------> SW2,
so that they can exchange BPDU's and participate in STP, and form 802.1q trunks etc ??
The idea is to build a switching lab, to learn switching by sharing equipment.
Its NOT to pass data for production.
The only other alternative is to simply borrow SW2 from Lab2, and physically connect it to SW1.
But thats no fun !
I dont know too much about VPN's etc, but
Can this be achieved using a GRE tunnel over IpSec, and then bridging the gre / tunnel interface with a spare ethernet interface
on the routers ?
Any ideas if this is possible ?
