LACP between IOS XR router and QFX switch

[Saskiaaa]

Hello everyone,

im planning to config a LACP between XR Router and QFX switch. My questions
1- is my LACP connection is correct or the MUX  state must be ATTACHED  not DISTRIBUTING ? 

2- how i can config  ip address  ( Gateway ) for the aggregated Interface  on XR Router? 

 

QFX Switch  Configurations and Details:

set chassis aggregated-devices ethernet device-count 1

set interfaces ae0 aggregated-ether-options lacp active

set interfaces ae0 aggregated-ether-options lacp periodic fast

set interfaces ae0 unit 0 family ethernet-switching interface-mode access

set interfaces xe-0/0/4 ether-options 802.3ad ae0

set interfaces xe-0/0/5 ether-options 802.3ad ae0

Hello @Saskiaaa ,

on the QFX switch you have used Fast LACP timers , on the XR side they are slow I think this is the only fix you need

>> set interfaces ae0 aggregated-ether-options lacp periodic fast

and

>>

LACP protocol:        Receive State  Transmit State          Mux State

      xe-0/0/4                  Current   Slow periodic Collecting distributing

      xe-0/0/5                  Current   Slow periodic Collecting distributing

Hope to help

Giuseppe

Hello @Giuseppe Larosa,

thank you for your replay, i have already configured the periodic fast on FQX, but sometimes display slow and sometime fast  

for set ip address  ( gateway ) on XR, its  so correct? 

interface Bundle-Ether200

ipv4 address 10.100.28.1 255.255.255.

Hello @Saskiaaa ,

the configuration of the Bundle-ether200 is correct on the XR side

Hope to help
