Local VPLS

Just started working with service routers, mostly ALU 7750 kind. I'm having difficulties wrapping my head around some of the concepts.

I believe this question pertains to most vendors, not just ALU. No fancy stuff here, no MPLS etc.

​

I want to send tagged traffic (vl10) on port 1/1/1 to vl10 on another port 1/1/2 and back.

Do I understand concept of local VPLS correctly, that it creates virtual L2 switch and could bridge my ports without any additional tricks?

​

Something like:

service vpls 1000

sap 1/1/1:10 (sap represents port in ALU concept)

sap 1/1/2:10

should work right away?

I understand on ingress all tags are stripped and on egress added back depending on port/sap tagging, so similarly it could "translate vlans" as well?

​

service vpls 2000

sap 2/2/2:500

sap 1/1/6:300

​

interconnecting traffic in vl500 and 300?

​

Thanks a lot.
