[nsp] strange behavior (juniper to switch to switch to customer)

[Jan Czmok]

I have a strange issue:

i have a juniper m10 which is connected to a catalyst 4006 which is
connected to a 2950 switch and then to a customer.

What i would like to archieve:
------------------------------

on customer side: ethernet port untagged.
on our entry side of the 2950, tag the port with vlan 110
transport it over the 4006 to the juniper.

what does not work:
-------------------
the above scenario :-( i can either the mac adresses but ping does not
work

the configuration:
------------------

juniper(r5.3):
==============

description "VLAN 110";
vlan-id 110;
family inet {
    address x.x.x.1/30;
    }

cat4006:

any clue, why it DID NOT work ?
