Configuring BGP-based auto-discovery for VPLS

Changing or clearing the local AS number when VPLS auto-discovery is enabled
When VPLS auto-discovery is enabled on the device and the user wants to clear or change the BGP
local AS number, the user must first disable VPLS auto-discovery, then clear the local AS number.
When the user attempts to clear or change the local AS number while VPLS auto-discovery is
enabled, the console displays the following message:
Brocade(config-bgp)# no router bgp
Error: VPLS instances with BGP auto-discovery exist, remove auto-discovery
configuration first!
To clear the BGP local AS number when VPLS auto-discovery is 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)# router bgp
Brocade(config-bgp)# no local-as 10
BGP is no longer operational
Syntax: [no] auto-discovery
Syntax: [no] local-as num
Disabling BGP4 when VPLS auto-discovery is enabled
When VPLS auto-discovery is enabled on the device and the user wants to disable BGP4, first
disable VPLS auto-discovery, then disable BGP4 at the VPLS instance level of the CLI. When the
user attempts to disable BGP4 while VPLS auto-discovery is enabled, the console displays the
following message:
Brocade(config-bgp)# no router bgp
Error: There are VPLS instances with BGP auto-discovery enabled, disable
auto-discovery first!
NOTE
When VPLS auto-discovery is not enabled on the device, the use can disable BGP simply by entering
the CLI command no router bgp at the global CONFIG level of the CLI.
To disable BGP4 when VPLS auto-discovery is 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)# no router bgp
router bgp mode now disabled. All bgp config data will be lost when writing to
flash!!
Syntax: [no] auto-discovery
Syntax: [no] router bgp
