#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

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.

#### 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
