Item Description
Syntax route-distinguisher ip-addr.comm-val | as-number:ext-comm-val
no route-distinguisher
Context configure>service>vpls>bgp
Description This command configures the Route Distinguisher (RD) component that will be signaled in the
MPBGP NLRI for L2VPN AFI. This value will be used for BGP-AD and BGP VPLS NLRI if these
features are configured.
If this command is not configured, the RD is automatically built using the BGP-AD VPLS ID.
The following rules apply:
• If BGP AD VPLS-id is not configured and no RD is configured under BGP node,
RD=VPLS-ID
• If BGP AD VPLS-id is not configured, an RD 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 RD value is also configured under BGP node, the
configured RD value prevails.
Values and format (6 bytes, other 2 bytes of type) will be automatically generated.
Default no route-distinguisher
Parameters ip-addr:comm-val — Specifies the IP address.
OR
as-number:ext-comm-val — Specifies the AS number.
