As shown in the figure, R1, R2, R3, and R4 are in the same PLs domain, and LDP is used to distribute IPLS labels between devices.
R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to achieve R1 access 4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be:____. (Please fill in the Arabic numerals directly, without symbols)

As shown in the figure, Sitel and Site2 need to achieve mutual access through the operator's BGP/MPLS IPVPN. A known The public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has The 192.168.1.0/24 network segment route is advertised to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal. When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Sitel, the outermost label What should the sign be?
FEC In/Out label
1.1.1.1/32 6662/3
FEC In/Out label
1.1.1.1/32 6662/3

In an operator's MPLSVPN network, there are two devices PE1 and PE2 for MPLSVPN data forwarding. PE1 receives a private network route of 172.16.1.0/24 from the client, and converts it to a VPNv4 route on PE1 and assigns a label of 1027 Released to PE2. The outgoing label of the MPLS LSR-ID of PE2 reaching PE1 is 1025o When a client on PE2 accesses 172.16.1.0/24, the frame sent by PE2, the inner and outer labels should be a combination of the following 6 options?

(Drag and drop question) The configuration shown in the figure is performed on R2 to filter all incoming routes. Suppose there is an entry on R1 AS_Path attribute is [100 200 300 400] BGP routes need to be sent to R2, please help network administrators in Adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be routed by R2 route^policy AS-PATH permit node 10 if-match as-path-filter BGP route-policy AS-PATH deny node 20 ip as-path-filter BGP permit A[A2]00 400 100_
