[j-nsp] MPLS/CCC with EX4200

[Jeff]

Hello list,

I have a couple of questions regarding CCC with EX4200 (or better), 
unfortunately the EX3300 does not support MPLS at all.

A ccc with just two EX4200 talking ospf and mpls with each other is 
quite easy and would look like this:

# show protocols connections
remote-interface-switch Test {
     interface ge-0/0/1.0;
     transmit-lsp to-MPLS-2;
     receive-lsp to-MPLS-1;
}

The corresponding interface is configured like this:

unit 0 {
     family ccc;
}


So far everything is working, both ports carry L2 traffic tagged and 
untagged like they should.

Question 1)

However, in this case both switches are directly connected to each other 
so I was wondering: how does the configuration look like if there are 3x 
EX4200 in place like this:

ccc interface <-> Switch A <-> Switch B <-> Switch C <-> ccc interface

Since I have only two EX4200 in my lab, I cannot test it and I'm quite 
unsure how a proper configuration looks like.


Quesion 2)

For my understanding, it is not possible to inject local vlans into the 
ccc? So that instead of two physical ports being member of the ccc, the 
ccc consists of 1 physical port and the other end is configured with a 
set of vlans?


Question 3)

Any chance to do ccc and ethernet-switching on the same physical 
interface? Didn't find any examples about that and I guess I will need 
some better device like QFX, the newer EX4300/EX4600 or MX?



If you are aware of a better way to do L2 transport services using 
EX3300 or EX4200, feel free to hint me.


Thanks in advance!
