Hi,
We have 2 locations.
Please see attached topology
The first one is the Main Office and the second one is the Data Center/Colocation.
We have 2 different ISP at the Main office ISP1 and ISP2.
ISP1 is connected to a Layer 3 SW on Port 1 and Port 2 and Port 3 from same SW goes to our Primary and secondary Firewalls.
ISP2 is connected to a Layer 3 SW on Port 1 and Port 2 and Port 3 from same SW goes to our Primary and secondary Firewalls also.
Both the Primary and secondary Firewall are connected to our stack SW which is the Core in a redundant way.
The Data Center/COLO has one ISP which is ISP3. ISP3 is connected to a Layer 3 SW and then to Firewall and then to our stack SW which is the Core.
The Ip range of the Main office is 21.21.21.0/21
The Ip range of the Data Center/COLO is 30.30.30.0/21
The 2 locations are connected using VPN 1. We use this connection mainly to do backups.
Now a new connection has been added to improve the transfer are for backups between these 2 locations.
The new connection is a Point to point layer 2 connection and on the main Office side it has been terminated on a Layer 3 SW provided by the ISP and on the Data Center it is LC fiber.
My questions are as follows:
Thanks

Layer 2 p2p I take as Layer 2 MPLS or Dark Fibre.
If that is Layer 2, I will use as Layer 2 (if this is a private circuit) to run some IGP - using SVI between DC and main office, use that a priority, and also run IGP over VPN, in case Layer 2 Link fails uses the VPN link, if this is Cisco use EIGRP, that support unequal links.
or tell us how is your routing exiting?

Hello everyone,
This project is on hold for now.
Sorry for inconvenience. I could not even test the suggestions.
Thanks
