Point2Point L2 migration to MPLS! Help needed!
Posted on 2017-12-07
We are currently going through a change of infrastructure and of service provider and I was looking for some advice on our situation.
The current network is provided as a "Lan Extension Service/Point 2 Point Layer 2" and goes through a second site:
Main Office -> Remote Office 1 -> Satellite Office 2
There are multiple subnets/VLANs within Satelite Office 2
Data VLANs within Office 2 are a mix of static and DHCP with IP helper pointing to remote end of LES (Main Office)
New provider is an MPLS solution
Remote Office 1 is being decomissioned
Is setting up a Site-to-site VPN from Main Office - Satellite Office 2 feasible with minimal impact? How could this be implemented successfully?
DHCP over IPSEC VPN (Cisco ASA's 5506) - will this work?
There is a plan for multiple S2S IPSEC VPNs for other services/sites
This is time critical and the transition should be seamless to the end users, however future change at Satellite Office 2 will see all clients go to DHCP.
Any advice or suggestions you can provide would be great!
