The following example removes the VLAN identifier 5 from the original VLAN list
(

vlan-id-list [ 1–10 ]

) and configures the bridge domain explicitly:

[edit routing-instance rtg-inst-10]
instance-type virtual-switch;
interface ge-7/3/0.0;
bridge-domains {

bd-vlan–5 {

vlan-id 5;

}
bd {

vlan-id [ 1–4 6–10 ];

}

}

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.

In other words, if

sales-vlan-100

was part of a bridge domain VLAN list and you wish to

configure it explicitly, you must use the same naming convention:

[edit]
bridge-domains {

sales-vlan-100 { # You must use this name explicitly

vlan-id 100;

}

}

The following limitations apply to automatic bridge domain configuration:

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.
