Hello,
Please review these requirements, the solution that's been proposed and whether you think it'll work or any other answers to the problem.
Site A
Workstations
Servers (Production)
Phone system (Production)
Wi-Fi
Printers
Internet breakout
Datacentre
Servers (Disaster Recovery)
Phone system (disaster recovery)
Internet breakout
Important - For a reason I haven't yet got to the bottom of the customer needs to 'spread' VLANs between the two sites.
They have a 1GB layer 2 point-to-point link between a switch at either end configured as a trunk port and would like a backup solution in the event of the p2p link failing. Rather than a second p2p link from another provider they'd like to use a VPN between the ASA at each site to trunk the VLANs as a backup.
Questions -
1) Would this work at all?
2) How would it work (L2TP or GRE?)
3) Is there a better way to achieve the backup via public internet?
Many thanks,
Dave

L2TP may do it
but this is not a good solution to extended L2 VLAN over Internet, and the question why they need to have a redundant path for L2 DR site the HA should take place in the case of the L2 link is down !!
if you have a WAN i would say using Nexus or ASR with OTV could be an option as well for L2 expansion over a L3 network
hope this help
