Automatic CRL revocation using OCSP for an IPsec connection

We currently have an IPsec implementation to secure connection from F5 > RHEL boxes. Whilst reading the LTM configuration guide, I understand that OCSP is supported for TLS connection by setting up a profile, however similar setup for OCSP seems to be not available when configuring IPsec connection with a Peer.

Could someone please guide us with this subject? Either confirm whether this is not possible when using IPsec or perhaps provide us an alternate solution using OCSP not CRL.

Thanks RG
