Configuring BGP-based auto-discovery for VPLS

Viewing the loopback Interface
Use the show mpls ldp command to view the loopback interface and router ID in use on the
Brocade device. Refer to
“Displaying information about LDP”
791.
Configuring BGP4 to support VPLS auto-discovery
BGP4 must be enabled on the device and a local Autonomous System (AS) number must be
assigned before VPLS auto-discovery can be enabled.
This section includes configuration details for the following BGP-related tasks:
•
How to enable BGP4 and assign the local AS number
•
How to change or clear the local AS number when VPLS auto-discovery is enabled
•
How to disable BGP4 when VPLS auto-discovery is enabled
NOTE
This section provides minimal information about configuring BGP4 neighbors, peer groups, and
other essential BGP-related configuration tasks, because its focus is to provide information about
configuring BGP to support VPLS auto-discovery.
Enabling BGP4 and assigning the local AS number
In a VPLS configuration, all PEs in the same VPLS domain must be configured with the same AS
number. To assign a local AS number to the Brocade device, enter commands such as the
following.
Brocade(config)# router bgp
BGP4: Please configure 'local-as' parameter in order to enable BGP4.
Brocade(config-bgp)# local-as 10
Brocade(config-bgp)# neighbor 10.1.1.1 remote-as 10
These commands enable BGP4, set the local AS number to 10, and add the IP address of the
remote neighbor (10.1.1.1) to the IPv4 multi-protocol BGP neighbor table of the local router.
Syntax: [no] router bgp
Syntax: [no] local-as number
Syntax: [no] neighbor IPv4-address remote-as number
For local-as number, specify the AS number in which the Brocade device the user is configuring
resides.
For IPv4-address, enter the IP address of the remote neighbor.
For remote-as num, enter the AS number.
