L2 over L3

[fsarisac]

Hi,

I need some help to make the configuration below.

We have a point to point metroethernet line from our telecom between our two different locations. Behind the ME swithes of teelcom there is a 6513 switch in one side and a 3845 router at the other side. There is a SPA VPN module on 6513 and we are encrypting the traffic.

We need to pass L2 traffic (tagged) on this line. I want to use the same VLAN at the both side. Is it possible? How can I make the configuration?Any help will be highly appreciated.

Thanks

Hi, EoMPLS does transperent traffic flow over it. Thus this solution works for your case.

EoMPLS is an option but requires your ISP to run MPLS and configure the L2VPN for you.

Another option would be L2TPv3, which is a L2 tunnel on an IP network; basically same idea of EoMPLS without the need of MPLS.

Check some guide on that:
