Bgp Vpls Configuration Procedure - Nokia 7302 Manual

FD 100/320Gbps NT and FX NT IHub Services Guide
5.11.2
BGP VPLS configuration requires the setup of the MPLS infrastructure and VPLS
instance:
•
•
•
•
The provisioning of the BGP VPLS information is similar with the BGP AD for LDP
VPLS procedure:
•
•
•
•
The BGP VPLS parameters are provisioned at VPLS instance level, once for all
SDPs, automatically generating the SDP associations using a procedure similar with
the auto-binding in BGP-VPNs/BGP-AD. That is:
•
•
•
5.11.3
The pseudowire template concept used for BGP AD is re-used also for BGP VPLS
to dynamically instantiate pseudowire (SDP-bindings) and the related SDP
(provisioned or automatically instantiated).
On transmission the settings for the L2-Info extended community in the BGP Update
are derived from the pseudowire-template attributes. The following rules apply:

BGP VPLS Configuration Procedure

create LSPs
create SDPs if manually provisioned ones are required
create a VPLS service
configure interfaces and SAPs
configure Route Distinguisher, Route Target
configure pseudowire template to be used, eventually multiple mappings between
import RT and pseudowire template
the above information is reused also by BGP-AD
configure the local VE-ID
The MP-BGP Next Hop value is used to determine the Far End (FE) information.
The FE value is used to see if any SDP already exist to the remote PE.
If none exist, the equivalent SDP must be instantiated:
•
FE value is used to find any existing LSP to remote PE
•
SDP and pseudowire parameters from the related pseudowire template are used
Use of Pseudowire Template for BGP VPLS
If multiple pseudowire-templates (with or without import-rt) are specified for the
same VPLS instance the first pseudowire-template entry will be used.
Encaps Type is always 19 (13 in hex)
•
BGP VPLS supports only the Ethernet pseudowire type so the setting of vc-type
parameter in pseudowire-template is ignored and ether value is always used.
