Hi All,
I have 2 VSPs 4450 connected via V-IST working good.
I am trying to connect a ERS in both VSPs with MLT.
ERS = Standard MLT (Ports 1 and 2)
VSPs = SMLT (Port 12 each switch)
When I leave MLT connection on the VSP as standard it works good but when I enable the SMLT I lost connection.
Any suggestions?

Normally we recommend to use the penultimate byte to enumerate the nodes and then we normally make the smlt-virt-bmac same as bmac of one of the VSP nodes with 'ff' as last byte. Though your config should also work.
If you have connectivity problems I would start by looking at the VLAN MAC-table on the VSPs for the ERS MAC at hand to see what is wrong.
code:
VSP8200-1:1#% cfg||82:?bb
alias% show running-config -ib ||82:?bb
config terminal
lacp smlt-sys-id 82:bb:00:00:31:32
router isis
spbm 1 smlt-virtual-bmac 82:bb:00:00:31:ff
spbm 1 smlt-peer-system-id 82bb.0000.3200
exit
router isis
system-id 82bb.0000.3100
exit
end

It means that you could have a core link being NNI + SMLT at the same time. This capability however was only useful in migrating to SPB, existing networks based on ERS8000 where SMLT was used in the core with Square and Mesh topologies; the VSP9000 inherited the same capability, but this was then dropped on newer VOSS VSPs, since it was no longer needed as the more recent VSPs are pretty much always deployed with SPB to start with. It is not related the post at hand.

Hi Philip,
I can't recall any actual limitation like this. You can find SMLT description, guidelines and configurations steps in one of VOSS reference documents with no such limitations. BTW, I've got this from VSP 7200 Doc Collection... 😉
From here: https://www.extremenetworks.com/support/documentation/vsp-operating-system-software-voss-8-0-x/

Hope that helps,
Tomasz

Thought this might be related but I could be wrong - This document https://downloads.avaya.com/css/P8/documents/100181081 has a slide (slide number 17 shown below:
