I've been advised not to as well but I don't see how it could be an issue unless the concern is that some event downstream impacts your ICCP.
It sounds like a good practice not to, but that said I have a few environments where the ICCP VLAN was trunked downstream without any issues.

Hi Smicker,
I have additional question. Most all the sample config of MC-LAG, i can see they not allow vlan that use for ICCP at interface facing to downstream. In mean they just put vlan for iccp on back-to-back only between MX to MX. Is it have an issue if we put vlan for iccp at interface facing to downstream? I'm check on inetzero also some blog and they not put vlan ICCP on that interface.
Thanks and apreciate any feedback.
