flowing out of MPLS network, and make advertises to the upstream
LSR. Thus upstream LSR will forward the traffic from the MPLS net-
work in the form of IP packets (or explicitly popup label packets).
There are two kinds of control policies: based on destination net-
work segment and based on next hop.
1. The egress control policy based on destination networks (mpls
ldp egress for <prefix-access-list>) directly specifies which
destination where local LSR is terminated.
2. The egress control policy based on next hop (mpls ldp egress
nexthop <nexthop-access-list>) specifies which neighbors
are non-MPLS routers so that the traffic of these neighbors
as next hops is the traffic out of MPLS. Local router allocates
popup labels for this traffic.
As long as a route meets either of the two policies, that is, the
destination prefix is permitted by <prefix-access-list> or the next
hop is permitted by <nexthop-access-list> , the LDP will allocate
a popup label to it.
The policy takes effect only on the refreshed FECs after the config-
uration and does not reallocate labels to the existing FECs. There-
fore, it is not recommended to configure this command when the
system is running to avoid inconsistency.
1. The router allocates popup labels to all subnet routes in net-
works 10.101.0.0/16 and 10.221.0.0/16, and allocates popup
labels to all subnet routes in network 10.222.0.0/16 but not in
10.222.1.0/24.

2. The router allocates popup labels to all destination networks
whose next hop are 100.1.1.3:
ZXR10(config)#ip access-list standard 11
ZXR10(config-std-nacl)#permit 100.1.1.3 0.0.0.0
ZXR10(config-std-nacl)#exit
ZXR10(config)#mpls ldp egress nexthop 11

Use this command to set the compatibility of the label advertise-
ment mode. To disable this feature, use the no form of this com-
mand.
Global configuration

mpls ldp enable connect-with-dod

no mpls ldp enable connect-with-dod
Use this command to make the router to interconnect with LSR
adopting the DOD mode.
