1.两个ASBR(VMX4-P4,VMX5-P5)各有EBGP和IBGP连接,协议族bgp-lu(family inet labeled-unicast)
为两个PE（10.0.255.1，10.0.255.6)提供labeled route
2.PE的IBGP( family inet labeled-unicast resolve-vpn), resolve-vpn表示将labeled route放在int.3,为跨域(inter-AS)PE之间的VPNV4路由的下一条提供解析
Allow labeled routes to be placed in the inet.3 routing table for route resolution. These routes are then resolved for PE router connections where the remote PE is located across another AS. For a PE router to install a route in the VRF, the next hop must resolve to a route stored within the inet.3 table.
resolve-vpn—(Optional) Store labeled routes in the inet.3 or inet6.3 routing table to resolve routes for a provider edge (PE) router located in a different autonomous system (AS). For a PE router to install a route in the virtual routing and forwarding (VRF) table, the next hop must resolve to a route stored in the inet.3 or inet6.3 routing table. This option is also used to configure inter-AS VPLS with MAC operations.
3.ASBR(VMX4-P4,VMX5-P5)之间在互相通告10.0.255.1/10.0.255.6时，其10.0.255.1/10.0.255.6是从ospf来的，在向各自的目的地PE转发包时，需set protocols mpls traffic-engineering mpls-forwarding（ospf用来寻址，mpls用来转发）
4.PE1-P3之间有个 ldp-tunneling over rsvp的隧道(set protocols ldp interface lo0.0)
5.juniper默认标签盏最大标签数为3,PE1需要set interfaces ge-0/0/0 unit 0 family mpls maximum-labels 4
