• B.The router sends BGP updates learned from its IBGP neighbors to its other IBGP neighbors and EPGP neighbors
• C.The router will be connected directly from its EBGP IBGP neighbor, otherwise, IBGP-Multi-hop must be configured
• D.IBGP neighbors can establish neighbor relationships through Loopback engagements
• E.The router sends BGP updates learned from its EBGP neighbors to its other IBGP neighbors and EBGP neighbors

Fill in Blank
As shown in the figure, R1, R2, R3, and R4 reside in the same MPLS domain, and LDP (Label Distribution Protocol) is used to distribute MPLS labels.
R4 is the egress LSR (Label Switching Router) for the FEC (Forwarding Equivalence Class) 4.4.4.0/24.
To make R4 aware of QoS forwarding priority of a packet sent from R1 and destined for 4.4.4.0/24, Without looking up R4's label forwarding information base, The outgoing label of the FEC on R3 should be _____ (Enter an Arabic numeral without symbols).
