Description This command configures the route target (RT) component that will be signaled in the related MP-
BGP attribute to be used for BGP auto-discovery, BGP VPLS and BGP Multi-Homing if these
features are configured in this VPLS service.
If this command is not used, the RT is built automatically using the VPLS ID. The ext-comm can
have the same two formats as the VPLS ID, a two-octet AS-specific extended community, IPv4
specific extended community.
The following rules apply:
Parameters
export ext-community — Specify communities allowed to be sent to remote PE neighbors.
import ext-community — Specify communities allowed to be accepted from remote PE neighbors.
vpls-id
Syntax vpls-id vpls-id
Context config>service>vpls>bgp-ad
Description
This command configures the VPLS ID component that will be signaled in one of the extended
community attributes (ext-comm).
Values and format (6 bytes, other 2 bytes of type-subtype will be automatically generated)
Parameters vpls-id — Specifies a globally unique VPLS ID for BGP auto-discovery in this VPLS service.
vsi-export
Syntax vsi-export policy-name [policy-name...(up to 5 max)]
no vsi-export
Context config>service>vpls>bgp-ad
config>service>vpls>bgp
Description This command specifies the name of the VSI export policies to be used for BGP auto-discovery, BGP
VPLS and BGP Multi-Homing if these features are configured in this VPLS service. If multiple
policy names are configured, the policies are evaluated in the order they are specified. The first
policy that matches is applied.
7750 SR OS Services Guide
• if BGP AD VPLS-id is configured & no RT is configured under BGP node - RT = VPLS-ID
• if BGP AD VPLS-id is not configured then an RT value must be configured under BGP node
(this is the case when only BGP VPLS is configured)
• if BGP AD VPLS-id is configured and an RT value is also configured under BGP node, the con-
figured RT value prevails
Values
vpls-id : <ip-addr:comm-val>|<as-number:ext-comm-val>
ip-addr a.b.c.d
comm-val 0 — 65535
as-number 1..65535
