Regarding MP-BGP, which of the following descriptions is wrong?

In the process of establishing an LDP session, the active party will first send Initialization information to negotiate parameters. If the passive party does not accept the negotiated parameters, it will send it.

As shown in the figure, R1, R2, R3, and R4 are in the same MPLS domain, and LDP is used to allocate MPLS labels between devices. R4 is the FEC Egress LSR of 4.4.4.0/24. If you want to realize that when R1 accesses 4.4.4.0/24, R4 does not need to query the label table but can understand the forwarding priority of the data, then R3's outgoing label for the FEC should be (). (Please fill in the Arabic numerals directly, without symbols)
