Is that possible to create two Policy Based VPN's with two ISP's , so that if one ISP fails then traffic will failover to the VPN tunnel created on other ISP.
I have few subnets for which I want to use VPN1 and for few subnets I want to use VPN2. This can be achieved by creating policy based VPN And both VPN will be backup for each other if any of the ISP fails.
As an example
VPN1-G0/0/0 -ISP1- IP-x.x.x.x
VPN2-G0/0/1 -ISP2- IP-y.y.y.y
Encryption domain:
10.0.1.0/24- It should use VPN1, if ISP1 fails the it should use VPN2
10.0.2.0/24- it should use VPN2, if ISP2 fails then it should use VPN1
How can we achieve Automatic failover in Policy based VPN ,please share you suggestions or any supporting doc.
