That would be a great application for l2tpv3, assuming you don't need to
move a huge amount of data and don't have MPLS enabled.

Hit me up off-list for the config examples.

Subject: [c-nsp] Bridge L2 network across WAN

Hi Everyone,

 

I am hoping someone can help me out here. We have an old legacy network
which is just a flat L2 network across multiple sites connected by
fibre. For various reasons this fibre will no longer be available for
use, so I need to find another way to keep this L2 network intact. There
is a routed network between all the buildings, so I am hoping there is
some sort of bridge scenario to carry this L2 traffic across.

 

My plan at the moment was to connect these l2 switches at the sites into
a 2811 at each site which in turn will be connected into the routed
network. So basically I am after a way to bridge this l2 network across
the 2811's/routed network.

 

Any help would be extremely appreciated.

 

Regards,

 

Nikolas Geyer.
