[j-nsp] Double-tagging on EX

[Harold 'Buz' Dale]

Are you really wanting to double tag (like QinQ?) or just trunk two vlans over one link?  What exactly are you trying to accomplish?
Luck,
Buz

Hi
While thinking about how to do it, I was wondering what is the requirement of this? 
You have packets from two different VLAN untagged and going out through a tagged interface. But this tagged interface should be part of the two VLAN and this packets should be placed in the respective VLAN. 

How can the packet be tagged with two VLAN id? Wats the requirement?

Hi,

We need to double-tag packets on an EX4200, i.e., untagged packets come in on one interface, and packets with two VLAN tags come out of another interface.  So far, everything we tried has failed.  Has anyone figured out how to do this?

Juniper documentation is useless, as always.


Thanks!


Alex
