I am facing issue about getting LACP message to pass through MX204. Below is the topology:
I have Juniper MX204 as PE router with MPLS enabled. I have a requirement which needs to configure LACP between QFX switches by passing through MX204. So, I am writing for idea/solution to make that happen.
set interfaces xe-0/0/0 encapsulation ethernet-ccc
set interfaces xe-0/0/0.0 family ccc
set interfaces xe-0/0/1 encapsulation ethernet-ccc
set interfaces xe-0/0/1.0 family ccc
set protocols connections interface-switch XCON-1 interface xe-0/0/0.0
set protocols connections interface-switch XCON-1 interface xe-0/0/1.0
set protocols mpls interface xe-0/0/0.0
set protocols mpls interface xe-0/0/1.0
I hope You do know that according to standards LACP PDUs are untagged so passing LACP with VLAN tag is not supported.
Thank you very much for your input. I have tested the configuration you provided and it works.
However, I have found another solution which can also bring up LACP between end to end switches.
set interfaces xe-0/0/0 encapsulation ethernet-bridge
set interfaces xe-0/0/0 unit 0 input-vlan-map push
set interfaces xe-0/0/0 unit 0 input-vlan-map vlan-id 123
set interfaces xe-0/0/0 unit 0 output-vlan-map pop
set interfaces xe-0/0/1 encapsulation ethernet-bridge
set interfaces xe-0/0/1 unit 0 input-vlan-map push
set interfaces xe-0/0/1 unit 0 input-vlan-map vlan-id 123
set interfaces xe-0/0/1 unit 0 output-vlan-map pop
set bridge-domains VL123 interface xe-0/0/0.0
set bridge-domains VL123 interface xe-0/0/1.0
Any advices or idea about pro and con between these two configuration template?
