IPSec - crypto map multiple peers

When configuring a VPN using IPSec with a crypto map, it is possible to configure multiple peers for redundancy. This can be done like so:

crypto map mymap 10 ipsec-isakmp
 set peer 2.2.2.2
 set peer 3.3.3.3

In the above configuration 2.2.2.2 will be the primary peer while 3.3.3.3 will be the secondary peer.
