How to reserve a DMVPN?
Hello, there is a task to reserve DNVPN using the second ISP. The central office is located in the city of Stavropol and two branches in Moscow and St. Petersburg. The central router of Stavropol is the Hub and the Spoke branches.
Now everything is configured through one ISP (ISP1), but the boss decided to make a reservation and connected the second channel (ISP2).
As I understand it, it is necessary to raise one tunnel in the branches and one more Hub on the central one.
The question is how to connect all this with IP SLA and OSPF? And how to configure the Hub correctly?
HUB config!
