Example: Configuring Multiple Bridge Domains with a VLAN ID List

To configure multiple bridge domains with one statement, include the vlan-id-list statement at the [edit bridge-domains] hierarchy level.

You can configure these bridge domains in a virtual switch routing instance. However, if a VLAN identifier is already part of a VLAN identifier list in a bridge domain under a routing instance, then you cannot configure an explicit bridge domain with that VLAN identifier. In other words. there can be no overlap between a VLAN identifier list and another VLAN identifier configuration.

If a VLAN identifier is already part of a VLAN identifier list in a bridge domain under a routing instance, then you must delete the VLAN identifier from the list before you can configure an explicit or “regular” bridge domain. Also, the explicit bridge domain will not perform properly unless it has the same name as the bridge domain in the VLAN identifier list.

• Only one vlan-id-list statement is allowed in a routing instance.
• Bridge options are not supported with the vlan-id-list statement.
• Only trunk interfaces are supported.
• There is no support for integrated routing and bridging (IRB).

You display the status and other parameters for automatic bridge domains configured with the vlan-id-list statement using the same show l2-learning instance command as used for individually configured bridge domains.
