Configuring BGP-based auto-discovery for VPLS

Viewing the route target for a VPLS instance
Use the show mpls vpls name command to view the route targets for a VPLS instance. Refer to
“Displaying information about VPLS auto-discovery and load balancing”
Enabling and disabling load balancing for a VPLS instance (optional)
This section describes how to enable and disable load balancing for a VPLS instance on which
VPLS auto-discovery is enabled. When load balancing is enabled, the Brocade device automatically
load balances traffic to all auto-discovered peers.
The user can configure a VPLS instance to load balance known unicast traffic sent to
auto-discovered VPLS peers across multiple tunnel LSPs. The CLI commands for enabling and
disabling load balancing differ depending on whether VPLS auto-discovery is enabled on the VPLS
instance. Follow the appropriate procedures in this section.
NOTE
The Brocade device load balances traffic for auto-discovered VPLS peers, the same as for
manually-created VPLS peers.
Enabling load balancing when VPLS auto-discovery is disabled
To enable VPLS auto-discovery and load balancing of traffic sent to auto-discovered VPLS peers,
enter commands such as the following:
NOTE
Before enabling VPLS auto-discovery, make sure the user has completed the configuration tasks
listed in
762.
Brocade(config)# router mpls
Brocade(config-mpls)# vpls c1 10
Brocade(config-mpls-vpls-c1)# auto-discovery load-balance
Syntax: [no] auto-discovery load-balance
To disable load balancing, refer to
Enabling load balancing when VPLS auto-discovery is enabled
When VPLS auto-discovery is enabled for a VPLS instance and the user wishes to enable load
balancing, the user must first disable VPLS auto-discovery, then re-enable it with the
load-balancing option. When the user attempts to enable load balancing when VPLS
auto-discovery is enabled, the console displays the following message:
Brocade(config-mpls-vpls-c1)# auto-discovery load-balance
Error: Please disable auto-discovery before make change!
To enable load balancing for a VPLS instance that has VPLS auto-discovery enabled, enter
commands such as the following.
Brocade(config)# router mpls
Brocade(config-mpls)# vpls c1 10
Brocade(config-mpls-vpls-c1)# no auto-discovery
Brocade(config-mpls-vpls-c1)# auto-discovery load-balance
