Information About PKI Split VRF in Trustpoint

Overview of PKI Split VRF in Trustpoint

The PKI Split VRF in Trustpoint feature allows you to configure VPN Routing and Forwarding (VRF) for certificate enrollment and for certificate revocation list (CRL) checking. The VRF is configured in the enrollment profile using the enrollment url command under the crypto pki profile enrollment command to attach the enrollment profile to a trustpoint. You can configure the same VRF for enrollment and CRL or configure different VRFs. Based on the configuration (enrollment or revocation), the corresponding VRF is selected and Simple Certificate Enrollment Protocol (SCEP) request is sent via the respective VRF.

To configure enrollment and CRL via different routing paths, you must configure the enrollment url command using the crypto pki profile enrollment command. This configured VRF acts as an enrollment VRF and the enrollment request goes via that VRF. However, the CRL uses the global VRF configured in the trustpoint using the

If no VRF is configured in the enrollment url command, the enrollment takes global enrollment that is configured in the crypto pki trustpoint command.

Configuring the Split VRF

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. crypto pki profile enrollment label
  4. enrollment url url [vrf vrf-name]
  5. exit
  6. show crypto pki profile
  7. show crypto pki trustpoint

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:

Device> enable
Enables privileged EXEC mode.
  • Enter your password if prompted.
Step 2

configure terminal

Example:

Device# configure terminal
Enters global configuration mode.
Step 3

crypto pki profile enrollment label

Example:

Device(config)# crypto pki profile enrollment pki_profile
Defines an enrollment profile and enters ca-profile-enroll configuration mode.
  • label —Name for the enrollment profile; the enrollment profile name must match the name specified in the enrollment profile command.
Step 4

enrollment url url [vrf vrf-name]

Example:

Device(ca-profile-enroll)# enrollment url http://entrust:81/cda-cgi/clientcgi.exe vrf vrf1

Specifies the URL and the VPN Routing and Forwarding (VRF) of the CA server to which to send certificate enrollment requests via HTTP or TFTP.

Step 5

exit

Example:

Device(ca-profile-enroll)# exit
Exits ca-profile-enroll configuration mode.
  • Enter this command a second time to exit global configuration mode.
Step 6

show crypto pki profile

Example:

Device# show crypto pki profile
(Optional) Displays information about PKI profile.
Step 7

show crypto pki trustpoint

Example:

Device# show crypto pki trustpoint
(Optional) Displays information about PKI trustpoints.

Enrollment and Certificate Revocation List Via Same VRF

The following example shows how to configure the enrollment and certificate revocation list (CRL) via the same VRF: 

crypto pki trustpoint trustpoint1
	enrollment url http://10.10.10.10:80
	vrf vrf1
	revocation-check crl

Enrollment and Certificate Revocation List Via Different VRF

The following example shows how to configure the enrollment and certificate revocation list (CRL) via different VRF: 

crypto pki profile enrollment pki_profile
 enrollment url http://10.10.10.10:80 vrf vrf2

crypto pki trustpoint trustpoint1
 enrollment profile pki_profile
 vrf vrf1
 revocation-check crl
