The IOS documentation for the crypto map command gives the syntax as
crypto map [ipv6] map-name seq-num [ ipsec-isakmp [ dynamic dynamic-map-name | discover | profile profile-name ] ]
I have a 881w ISR. In what different situations do we use the ipsec-isakmp dynamic form as opposed to the ipsec-isakmp profile form?
I understand that ipsec-isakmp profile is applied directly to the vpdn-group. Does this substitute for applying the crypto map directing to the WAN interface? Why would I want to do that?
