MC-LAG multi-homing for native PBB

This section describes a configuration example for BEB C configuration with the following assumptions:

service pbb
source-bmac ab-ac-ad-ef-00-00
port 1/1/1
ethernet
encap-type qinq
lag 1
port 1/1/1 priority 20
lacp active administrative-key 32768
redundancy
multi-chassis
peer 1.1.1.3 create
source-address 10.1.1.1
mc-lag
lag 1 lacp-key 1 system-id 00:00:00:01:01:01 system-priority 100
source-bmac-lsb use-lacp-key 
service vpls 100 bvpls
sap 2/2/2:100 // bvid 100 
mac-notification
no shutdown

service vpls 101 bvpls
sap 2/2/2:101 // bvid 101
mac-notification
no shutdown
// no per BVPLS source-bmac configuration, the chassis one (ab-ac-ad-ef-00-00) is used

service vpls 1000 ivpls
backbone-vpls 100
sap lag-1:1000 //automatically associates the SAP with ab-ac-ad-ef-00-01 (first 36 bits from BVPLS 100 sbmac+16bit source-bmac-lsb)

service vpls 1001 ivpls
backbone-vpls 101
sap lag-1:1001 //automatically associates the SAP with ab-ac-ad-ef-00-01(first 36 bits from BVPLS 101 sbmac+16bit source-bmac-lsb)
