IPSec Preferred Peer

Supported platforms: Cisco 1710, 1721, 1751, 1751-V, 1760; supported in all legacy images containing IPSec 3DES images (K9 images) and Advanced Security, Advanced IP Services and Advanced Enterprise Services
cross-platform images.

IPSec Preferred Peer gives greater control in specifying if a peer in an IPSec crypto map will be activated as a backup in the case of failure.

When defining multiple peers in a crypto map, if the first peer is designated "Default", it prevents the advancing of peers from being triggered by a DPD failure. Only retransmits or idle timer-based failures will advance to the next peer.
