Bridging over a VPN Tunnel

[joet8591]

Is bridging supported or possible across an IPsec tunnel using routers? (Need to bridge some IP traffic)

I heard about it's possible, so you get double tunneling.

I was thinking IRB/CRB. Trying to get the Vlan/subnet extended to the other router across a VPN. (The tunnel interface did not support the bridging command.)

Thanks

hmm wonder how it will be supported ? you dont have any ip to encrypt it to or will you bridge to GRE and encrypt it ?

To be honest I don't know but I think it's possible to make the second tunnel like no one did. But maybe it's about:

Computer---Computer-----Computer-----Computer

1VPN ------ 2VPN ------ 2VPN ------- 1VPN
