Controls how the router checks certificate revocation
lists (CRLs) when determining whether to accept a peer's certificates.
The no version restores the default setting.
Note:
This command is replacing the ike crl command. The ike crl command may be
removed completely in a future release.
Options
ignored—Specifies that the router will not try
to find or use CRLs
optional—Specifies that the router will try to find
a CRL. If a CRL is found, the peer certificate must not appear in
the CRL. If no CRL is found, the peer can still authenticate; this
is the default.
required—Specifies that the router must find a valid
CRL; the CRL must be current, and the peer certificate must not appear
in the CRL
