When working with CISCO router based IPSEC VPN tunnels, we might need to enable HA feature for the continuous connectivity with the remote peer. By default, we use just a single peer IP address. But if the remote peer is dead for some reason, we face issues with IPSEC tunnel failure. In order to mitigate that risk, we can use the feature called “default peer” . What it does is, it enable us to define multiple redundant peers instead of a single peer.
