Hi,
Not sure if I'm "doing the dumb" or Junos bug or limitation of the QFX /
Trident 2+ chip-set.
Trying to do a basic l2circuit as follows
VLAN Tagged Interface > MX204 l2circuit / ldp > QFX-5110 / ldp >
QFX-5110
l2circuit / ldp > VLAN Tagged Interface
What I am seeing is traffic going Test Device > QFX-5110 > QFX-5110 >
MX204
Test Device arrives fine.
Return path from Test Device > MX204 > QFX-5110 > QFX-5110 > Test
Device is
broken.
Config is as follows
*MX204 Port facing test device on VLAN tag 123*

On the* MX end test equipment *I can see the MAC address learned from
the *QFX
end test equipment*, however on the *QFX end test equipment* I cannot
see
the MAC address of the* MX end test equipment*.
The MX's and QFX's are running Junos: 18.4R1-S3.1
Not sure if I just have this configured wrong, or a QFX chippie
limitation
or a Junos bug.
Any help / pointers would be appreciated :)
