2.13.11 Example for Configuring LDP GTSM
This section provides an example for configuring LDP GTSM. The procedure consists of
enabling MPLS and MPLS LDP on each device and each interface and configuring LDP GTMP
on both LDP peers.
Networking Requirements
As shown in Figure 2-16, each node runs MPLS and MPLS LDP. GTSM needs to be enabled
on LSR B.

Configuration Roadmap
The configuration roadmap is as follows:
l Configure basic MPLS and MPLS LDP functions.
l Configure GTSM on the two LDP peers.
Data Preparation
To complete the configuration, you need the following data:
l LSR ID of each LDP peer
l Maximum number of valid hops permitted by GTSM
Procedure
Step 1 Configure an IP address for each interface. The configuration details are not provided here.
Step 2 Configure OSPF to advertise the network segments connected to the interfaces of the LSRs and
host routes of LSR IDs. The configuration details are not provided here.
Step 3 Configure each device with MPLS and MPLS LDP functions on each interface. The
configuration details are not provided here.
After completing the preceding configurations, run the display mpls ldp session command on
each node to view the setup of LDP sessions. In the following example, the display on LSRA is
used.
<LSRA> display mpls ldp session
LDP Session(s) in Public Network
Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
A '*' before a session means the session is being deleted.
