Example :

Configuration :
312 evptree Rooted Multipoint aaa
Device UNI Role VLANs (click to edit)

CE 3 ens5 root 13, 14
ens6 leaf 31, 32
CE 2 ens5 root 15, 16, 84, 86
ens6 leaf 51, 61, 77
CE 1 ens5 root 1, 2
ens6 leaf 11, 12
CE 4 ens5 root 100, 103
ens6 leaf 101, 105

Take a look on group:229911 - 3 times (CE 2 ens 6 - we have 3 vlans - 51, 61, 77)
