Actually JNPR won't do any VLAN manipulation on CCC ports by default.
Only reason it works, is because Cisco end had same VLAN number and
Cisco was reinjecting the same SVLAN number, even though config was
'pop symmetric', which probably isn't 100% guaranteed/stable behaviour
(I know ES+ in 7600 will push the internal VLAN instead).
