VPLS switch instance

[cisco_raj]

Hi Friends.

Consider a scenario for single metro H-VPLS:

CE1-->MTU-s-->PE-RS1-->PE-RS2

|

|

PE-RS3

A single spoke Pseudowire is setup between the MTU-s and PE-RS1. Will there be a unique VCID for this Pseudowire???Say if there's one more MTU say MTU-s' connecting to PE-RS1, will there be two different Pesudowires and virtual circuits setup between PE-RS1 to MTU-s and PE-RS1 to MTU-s'?????Will there be two differnt VPLS switch instance for connectivity between PE-RS1 and MTU-s and PE-RS1 and MTU-s'????

I'm unable to understand the difference between Single spoke Pseudowire,Virtual circuit and VPLS Switch instance!!!!!!

Thanx

RAJ

Hi Mithil,

That's fine. I'm trying to understand the concept. Well, ur pdf is useful I should say!!!

Lets take this a bit further.

Pseudo-wire point to point(only)

allows specific VLan(s)

doesnt learn Mac-addresses.

VPLS

Point to point(e-line)

point to multi-point(e-tree)

multipoint to multipoint(e-lan)

mac-addresses learned so if point to point use pseudo-wires.

use neighbor statements to control branches, and split-horizon to protect from loops

use mac-in-mac to control learned mac-address.
