Moving MPLS From VR to VR

By default, MPLS (Multiprotocol Label Switching) is enabled on the VR-Default virtual router (VR). You can operate MPLS in VR-Default or in any user VR, but MPLS only operates in one VR. If you want to use MPLS in a user VR, you must delete it from VR-Default first.

To delete MPLS from a VR, do the following:
1. Disable MPLS on the LSR as described in Enabling and Disabling MPLS on an LSR.
2. Disable MPLS on all VLANs and reset the MPLS configuration as described in Resetting MPLS Configuration Parameter Values.
3. Remove MPLS from the VR by entering the following command:
  configure vr vr-name delete protocol protocol-name
  Note
  When you enter the command to delete MPLS from a VR, the software displays a prompt to remind you that the MPLS configuration is lost when MPLS is deleted.
To add MPLS to VR, do the following:
1. Use the following command:
  configure vr name add protocol mpls
2. Add any other protocols that you want to use with MPLS.

After you add MPLS to a VR, you must configure and enable MPLS. MPLS commands operate only in the VR to which MPLS is added. An error message appears if you enter an MPLS command in a VR that does not support MPLS.
