Tip:
If there are multiple links between routers, these routers must
advertise the same transmission address on the corresponding in-
terfaces.
This example describes how to use the IP address of the interface
as the transmission address on the interface oc3_2/1, and set the
transmission address as 145.22.0.56 on the interface oc3_4/1.

mpls ldp egress

Use this command to control LDP to allocate popup labels to the
designated indirectly connected destination networks (that is, the
egress control policy). To disable this feature, use the no form of
this command.
Global configuration
mpls ldp egress {for <prefix-access-list>| nexthop <nexthop-
access-list>}
no mpls ldp egress {for | nexthop}
for <prefix-access-li
st>
nexthop <nexthop-a
ccess-list>
By default, LDP allocates popup labels only to the directly con-
nected networks and makes advertisements to the peer LSR.
By default, LDP allocates popup labels only to the directly con-
nected networks and makes advertisements to the peer LSR. For
destination networks not directly connected, LDP acquires the idle
label from the label pool as the incoming label and chooses the
label value in the mapping message sent by the next hop of the
route as the outgoing label.
If local router is an edge LSR and the router of nexthop may be
a non-MPLS router, local LSR cannot bind the outgoing label, and
the received label packet be will discarded at the data layer be-
cause there is no outgoing label according to the MPLS framework
protocol.
In this case, it is necessary to configure the egress control pol-
icy to specify LDP to allocate popup labels to destination networks
