542 CHAPTER 49: BGP/MPLS VPN CONFIGURATION
By default, the vlan-id range of MPLS/VPN VLANs is from 0 to 1023, and the
default value of vlan-id is 0. The value range of vlan-id is from 1 to 3071.
c
CAUTION:
■ This command can only be executed on Trunk ports, and MPLS/VPN-enabled
VLANs and VLANs out of the configured range are excluded..
■ Set the VPN range for the cards and set the range of MPLS/VPN VLAN vlan-id
on the interface of the card to 1 to 4094.
Perform the following configuration in system view.
c
CAUTION:
■ This command is actually effective for only the first 12 ports on the card. When
you configure MPLS/VPN VLAN vlan-id on subsequent ports, only the
MPLS/VPN VLAN range enabled for one VLAN will take effect. If you remove
MPLS/VPN configuration from an active port, no subsequent port will take
effect automatically either, and you have to reconfigure the ports to update
their states.
■ Restart the card after issuing a command or its corresponding undo command
to ensure that the configuration takes effect.
■ After you cancel card configuration, if the VLAN configured on a port exceeds
1K, which is the default value, the configuration will be deleted automatically.
■ In aggregation mode, VPN-range configuration will not be synchronized
automatically and you can manually make/remove the configuration on an
individual port.
■ Set the VPN range for the ports and set the range of MPLS/VPN VLAN vlan-id
on the ports to 1 to 4094.
Perform the following configuration in Ethernet interface view.
