Configuring an Interface to Add a Specified VLAN ID to BPDUs
If multiple user networks are connected to the same interface of a provider edge (PE), configure the interfaces of customer edges (CEs) to add specified virtual local area network (VLAN) IDs to bridge protocol data units (BPDUs) before sending them to the PE. The VLAN IDs identify the user networks to which the BPDUs belong.
Procedure
- Run system-view
The system view is displayed.
- Run vlan vlan-id
A VLAN is created, and the VLAN view is displayed.
The VLAN ID ranges from 1 to 4094. To create multiple VLANs, repeat this step.
- Run quit
The system view is displayed.
- Run interface interface-type interface-number
The view of the interface connected to a PE is displayed.
- Run port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }
The VLAN ID that the CE allows to pass is configured.
- Run stp bpdu vlan vlan-id
The interface is configured to add the specified VLAN ID to BPDUs that will be sent to the PE.
Ensure that the specified VLAN ID is the same as that carried in BPDUs received by the interface.
- Run commit
The configuration is committed.
