3com 8807 Reference Guide

Use the undo vlan vpn-range command to restore the default MPLS label range 
for the card.

After vpn-range is enabled on the card, the range of MPLS/VPN VLAN vlan-id that 
can be configured on the 12 interfaces on the card is 4K, but not the default value 
of 1K.

Related command: port trunk mpls vlan.

■

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 the configuration on the card is canceled, 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.

Use the vpn-instance-capability simple command to configure a router as 
Multi-VPN-Instance CE.

Use the undo vpn-instance-capability command to cancel the configuration.

OSPF multi-VPN-instance is often run at a PE router. Therefore, a CE router, on 
which OSPF multi-VPN-instance runs, is called Multi-VPN-Instance CE. Though
