BGP Auto-Discovery Commands
bgp
Syntax bgp
Context config>service>vpls
Description This command enables the context to configure the BGP related parameters for both BGP AD and
BGP VPLS.
bgp-vpls
Syntax bgp-vpls
Context config>service>vpls
Description This command enables the context to configure the BGP-VPLS parameters and addressing.
max-ve-id
Syntax max-ve-id value
no max-ve-id
Context config>service>vpls>bgp-vpls
Description This command configures the allowed range for the VE-id value: locally configured and received in a
NLRI. Configuration of a VE-id higher than the value specified in this command is not allowed.
Also upon reception of a higher VE-id in an NLRI imported in this VPLS instance (RT = configured
import RT) the following action must be taken:
• a trap must be generated informing the operator of the mismatch.
• NLRI must be dropped
• no service labels are to be installed for this VE-id
• no new NLRI must be generated if a new offset is required for VE-id.
The no form of this command sets the max-ve-id to un-configured. The BGP VPLS status should be
administratively down for “no max-ve-id” to be used.
The max-ve-id value can be changed without shutting down bgp-vpls if the newly provisioned value
does not conflict with the already configured local VE-ID. If the value of the local-VE-ID is higher
than the new max-ve-id value the command is rejected. The operator needs to decrease first the VE-
ID before running the command.
The actions taken for other max-ve-id values are described below:
• max-ve-id value higher than all VE-IDs (local and received) is allowed and there are no effects.
