Configuring a topology group
17
The name option allows you to specify the VPLS instance that you are configuring into the topology
group by using the name of the instance.
The vlan-id variable is used with the vlan keyword to specify the VPLS VLAN being configured into
topology group. You can specify multiple vlan-id values or specify a range of VLANs using the to
option.
The inner-vlan option allows you to specify a VPLS dual-tagged (double-tagged) VLAN configuration.
NOTE
The inner-vlan option does not allow both outer VLAN ranges and inner VLAN ranges for a given VPLS
instance. Once an outer VLAN range is specified, the inner VLAN option is not allowed. However, if a
single outer VLAN is specified, the inner VLAN option and range is allowed.
NOTE
You cannot delete a topology master VLAN if the topology group has only VPLS VLAN members and
no Layer 2 VLAN members because the normal procedure for deleting a topology master VLAN is to
elect another Layer 2 VLAN as the new master. Because a VPLS VLAN cannot be a master VLAN, you
must have at least one Layer 2 VLAN as a member. If it does not currently exist, you must add a Layer
2 VLAN before deleting a topology master.
NOTE
A maximum of 4000 VPLS member VLANs can be added to a topology group.
Topology group support within an ESI
Topology groups can be configured with VLANs that are part of a user-defined ESI. (Consult
Table 72 to see which platform supports topology groups within an ESI.) When you configure
topology groups in such a scenario, both the master and member VLANs must be part of the same
ESI. If an ESI is not specified, the system assumes a reference to the default ESI. Below is an
example of configuring topology groups with VLANs that are part of a user-defined ESI.
Brocade(config)# topology-group 2
Brocade(config-topo-group-2)# master-vlan service-esi 2
Brocade(config-topo-group-2)# member-vlan service-esi 3
Brocade(config-topo-group-2)# member-vlan service-esi 4
Brocade(config-topo-group-2)# member-vlan service-esi 5
Brocade(config-topo-group-2)# member-group service-esi 2
The commands configure topology group 2 and add the following to it:
• VLAN 2 in ESI “service-esi” as master VLAN
• VLANs 3, 4, and 5 in ESI “service-ESI” as member VLANs
• Member VLAN group 2
Syntax: [no] topology-group group-id
This command creates a topology group. The group-id parameter assigns an ID in the range 1 to
255 to the topology group.
Syntax: [no] master-vlan esi-name vlan-id
