Need help with MC-AE on vMX

3 weeks ago

mc-ae.JPG

I configured MC-AE on the two vMX ([14.1R1.10]). The followings are verfication output:

root@vMX1# run show iccp

Redundancy Group Information for peer 192.168.101.2
  TCP Connection       : Established
  Liveliness Detection : Up
  Redundancy Group ID          Status

It looks fine, but the lacp interface only shows one, no remote interface

root@vMX1# run show lacp interfaces ae1

Hi gongyayu,

This is working as expected, you won't see the peer's interface in the LACP interfaces.

For some common MC-LAG issues, check this out:
https://www.juniper.net/documentation/en_US/junos/topics/task/troubleshooting/troubleshooting-mc-lag...

Hope this helps.

Regards,

As mentioned previously, it's expected. What you need to do is go to the remote peer switch. Then you should see both VMX1 and VMX2's member in LACP status

Yes, even though the MC-LAG peers appear to be as one single logical unit in the layer 2 network and we may think that both peers should should LACP status regarless of the peer node, each peers have it own control plane, for this matter, the LACP negotiation will only include the local LACP ports remote/peer.
