ASBR 3 in turn generates a new label, 50, to advertise with the VPN-IPv4 prefix to its
internal MP-BGP peer inside its autonomous system, AS 35. Indirect next hop 4.4.4.4 is
for the MP-IBGP peering between PE 4 (loopback address 4.4.4.4) and ASBR 3. Indirect
next hop 10.5.5.50 is ASBR 2.

In turn, ASBR 3 receives MPLS frames with label 50 (the in label) from PE 4 and sends
MPLS frames with label 44 (the out label) to ASBR 2.
PE 4 receives the VPN-IPv4 prefix with label 50:
