Hi Team,
Over this topology:
SLPP in COREs and SLPP-GUARd in edge ports on ERS-STACK1, but what about MLT ports (x,y)? Could I apply SLPP-GUARD over MLT? Is there any other option to detect loops in the MLT between stacks?
Thanks in advance.

Yes, you can do that.

HI EF1,
Yes you can apply SLPP-Guard on port, to send slpp packet to the Stack-2 and use slpp-guard on.
About a loop in MLT, what can generate it ? misconfiguration or config loss on stack-2 ?
About config loss, you should use LACP. If stack-2 have config trouble, link x or y or both will stay out of the mlt.
If you have any other use case of loop in the MLT, let me know.
regards,
TQU
