mpls ldp discovery
transport-address
Use this command to configure the transmission address parame-
ter carried in hello messages on the layer 3 interface. To disable
this feature, use the no form of this command.

interface
<ip-address>
By default, ZXR10 takes the router identifier as the transmission
address advertised in the hello message on the frame interface.
A TCP connection must be established before an LDP session is
set up between LDP routers, which requires every router know the
peer transmission address (IP address). The LDP discovery mech-
anism enables the LDP router to advertise its own transmission
address used for establishing TCP connection to the peer.
The advertisement of the transmission address can be explicit (that
is, the transmission address appears in the hello message) or im-
plicit (that is, there is no transmission address appearing in the
hello message). The receiver of hello messages takes the source
IP address of the hello message as the transmission address to set
up TCP connection with the sender.
The mpls ldp discovery transport-address command provides
a way to change the default behavior of the router. If the interface
parameter is used, LDP advertises the IP address of the interface in
the hello message on the interface. If the <ip-address> parameter
is used, the LDP advertises the designated IP address in the hello
message on the interface.
If the configuration of the transmission address is changed during
the precess of the running of the interface, ZXR10 router will delete
the current adjacency relationship on the interface. If there is no
other adjacent relationship maintaining the session maintained by
the current adjacent relationship on the interface (multiple links do
not exist), the session will be closed. The adjacency relationship
(and the session) will be reestablished after a hello message is
received from the peer.
