Using L2TP to bridge a subnet across a WAN

[Venison Mogambi]

Hi,

Our server guys want to extend a single /24 subnet between two geographically disparate sites. We have all kinds of infrstracutre between the two sites, including firewalls, WAN links, etc. Would L2TP be a good solution for this? My understanding is that L2TP allows you to tunnel a single L2 segment across a WAN, so that the devices on the segment appear to each other as if they're on the same LAN segment, even if they're thousands of miles from each other.

Without going into too much detail, does this sound like a good scenario to use L2TP?

Thanks.

Hi

this is the only option which you could leverage while extending your LAN network over the WAN if it a point to point connectivity.

You could confiure in two ways either by using encapsulation L2TPv3 if the transport network is IPv4 or using encapuslation MPLS if the transport network is MPLS.

You can check link which has demonstrated the basic functionality of extending LAN network.
