vpls single node and multi node

[mike18]

Hi Everyone,

I need to know how can i tell from config or CLI command that VPLS configured in 7750 is Single node or Multi node?

A single-node VPLS doesn't need SDPs (everything's local to the node) so you could check if there any SDPs associated with the VPLS service with "show service id <service-id> sdp".

I check this VPLS on oneof the noe Node

show service id 17020001 sdp

===============================================================================
Services: Service Destination Points
===============================================================================
SdpId Type Far End addr Adm Opr I.Lbl E.Lbl
-------------------------------------------------------------------------------
123:4294966611 Bgp* 10.0.16.123 Up Up 261752 262050
128:4294966811 Bgp* 10.0.16.128 Up Up 262114 262117
129:4294966810 Bgp* 10.0.16.129 Up Up 262100 262123
-------------------------------------------------------------------------------
Number of SDPs : 3
-------------------------------------------------------------------------------
===============================================================================

so now we can say that this VPLS is Multi node Right?

on same Node when i run below command

show service id 17020001 sap

===============================================================================
SAP(Summary), Service 17020001
===============================================================================
PortId SvcId Ing. Ing. Egr. Egr. Adm Opr
QoS Fltr QoS Fltr
-------------------------------------------------------------------------------
9/1/8:1700 17020001 1 none 1 none Up Up
9/1/9:1700 17020001 1 none 1 none Up Up
9/1/10:1700 17020001 1 none 1 none Up Up
-------------------------------------------------------------------------------
Number of SAPs : 3
-------------------------------------------------------------------------------


so now we can say that given VPLS 17020001 can be single node and multi node on same Node right?

There are SDPs to three other nodes (10.0.16.123, 10.0.16.128 and 10.0.16.129) so it's multi-node VPLS.

Many thanks For confirming that.
