Description This command configures the transport address to be used when setting up the LDP TCP
sessions. The transport address can be configured globally (applies to all LDP interfaces) or
per interface. The most specific value is used.
With the transport-address command, you can set up the LDP interface to the connection
that can be set to the interface address or the system address. However, there can be an
issue of which address to use when there are parallel adjacencies. This address selection
situation can also occur when there is a link and a targeted adjacency, since targeted
adjacencies request the session to be set up only to the system IP address.
The transport-address value should not be interface if multiple interfaces exist between two
LDP neighbors.
Depending on the first adjacency to be formed, the TCP endpoint is chosen. In other words,
if one LDP interface is set up as transport-address interface and another as transport-
address system, then, depending on which adjacency was set up first, the TCP endpoint
addresses are determined. After that, because the hello contains the LSR ID, the LDP
session can be checked to verify that it is set up and then the adjacency can be matched to
the session.
The no form of the command:
Default system
Parameters interface — specifies that the IP interface address is used to set up the LDP session
system — specifies that the system IP address is used to set up the LDP session

• at the global level, sets the transport address to the default value
• at the interface level, sets the transport address to the value defined under the global
level
between neighbors. The transport address interface cannot be used if multiple
interfaces exist between two neighbors, since only one LDP session is set up
between two neighbors.
