The following example shows how to configure crypto-map-based IKEv2 peers using the certificate authentication method between
a static crypto-map IKEv2 initiator, a dynamic crypto-map IKEv2 responder, and a CA server. The initiator configuration is
as follows:
crypto pki trustpoint ca-server
enrollment url http://10.1.1.3:80
revocation-check none
!
crypto pki certificate map cmap-1 1
subject-name eq hostname = responder
!
!
crypto pki certificate chain ca-server
certificate 02
