I have a cisco 1841 router which is connected to a partner site via site to site vpn.
Our partner has given us ip addresses of 2 remote peers that we can use to establish the site to site vpn for backup purpose.
On one occassion, our router was connected to 2 remote peers and it seem to cause our connection to fail. I removed connection to 1 of the remote peer and it works fine after that. Pls advise if concurrent connection to 2 remote peers will result in connectivity problem.
Below is a portion of the router config showing phase1 and phase2 config. Thks in advance.
