I have tried this configuration but it works only for communication between tagged interfaces :
untagged port :
# show configuration interfaces ge-2/0/0
encapsulation ethernet-vpls;
unit 0 {
family bridge {
interface-mode access;
vlan-id 700;
}
}
tagged port :
#show configuration interfaces xe-3/0/1
vlan-tagging;
encapsulation vlan-vpls;
unit 700 {
encapsulation vlan-vpls;
vlan-id 700;
family vpls {
}
}
