Проброс влана на JuniperMX80 через MPLS

Обычный вариант, используется targeted ldp сессия (без rsvp):

interfaces {
 ge-1/1/2 {
 vlan-tagging;
 mtu 1600;
 encapsulation flexible-ethernet-services;
 unit 698 {
 description " -- TEST vlan over mpls";
 encapsulation vlan-ccc;
 vlan-id 698;
 family ccc;
 }
}
}
 }
 interface all;
 }
 ospf {
 area 0.0.0.0 {
 interface all;
 }
 }
 ldp {
 interface lo0.6;
 }
 l2circuit {
 neighbor 3.3.3.3 {
 interface ge-1/1/2.698 {
 virtual-circuit-id 1;
 }
 }
 }
}

Второй вариант, c помощью VPLS, LDP сигнализации и irb интерфейсом. IRB можно сделать только с VPLS.
