Hi @Matt Dillon ,
do I need to add PRIMARY to the remaining Boundary Groups for the endpoints to receive updates?
First of all, we should check if these clients from SITE2, SITE3 and CMG need to receive the update, if not, it is not necessary to configure it.
If yes, we should add SUP to boundary groups of SITE2, SITE3 and CMG. Is MP shared between PRIMARY with SITE2, SITE3 and CMG? If yes, we just add primary site to SITE2, SITE3 and CMG. If not, we should add new SUP to SITE2, SITE3 and CMG.
