I need to deploy Site to Site redundancy with remote site pix 501 and main site 5510's. I understand defining multiple peers in the crypto map. The following is straight from cisco doc.
"You can define multiple peers by using crypto maps to allow for redundancy. This configuration is also most useful for site-to-site VPNs. If one peer fails, there will still be a protected path. The peer that packets are actually sent to is determined by the last peer that the PIX Firewall heard from (received either traffic or a negotiation request from) for a given data flow. If the attempt fails with the first peer, IKE tries the next peer on the crypto map list."
Question is, do you also have to define separate isakmp statements for each peer as well?
Dynamic crypto maps (this requires IKE) can ease IPSec configuration and are recommended for use with networks where the peers are not always predetermined. An example of this is mobile users (VPN clients), who obtain dynamically assigned IP addresses. First, the mobile clients need to authenticate themselves to the local PIX Firewall IKE by something other than an IP address, such as a fully qualified domain name. Once authenticated, the security association request can be processed against a dynamic crypto map that is set up to accept requests (matching the specified local policy) from previously unknown peers.
