Failover Using A Peer-Group - Avaya G250 Administration

Failover using a peer-group

The failover VPN topology utilizes a peer-group which lists a group of redundant peers. At any
point in time, only one peer is active and acting as the remote peer. An object tracker monitors
the state of the active peer. If the active peer is presumed dead, the next peer in the peer-group
becomes the active remote peer.
