26 Confidential and Proprietary Information of ZTE CORPORATION
This command is to show IP address (Transport IP address) used
to set up TCP link by LDP neighbors discovered on the interfaces.
To set up the session, router must get the reachable route to the
router, that is, it can ping address. "xmit/recv" means sending/re-
ceiving hello message on the interface, and they are indispensable.
This example shows the detailed LDP discovery information of R2.
ZXR10_R2#show mpls ldp discovery detail
Local LDP Identifier:
10.10.2.2:0
Discovery Sources:
Interfaces:
VLAN10 (ldp): xmit/recv
LDP Id: 10.10.1.1:0
Src IP addr: 10.10.12.1; Transport IP addr: 10.10.12.1
VLAN20(ldp): xmit/recv
LDP Id: 10.10.3.3:0
Src IP addr: 10.10.23.3; Transport IP addr: 10.10.3.3
To view LDP session, use the following command.
This example shows the LDP session information of R2. It must
set up LDP session between LSRs before distributing the labels.
ZXR10_R2#show mpls ldp neighbor detail
Peer LDP Ident: 10.10.1.1:0; Local LDP Ident 10.10.2.2:0
TCP connection: 10.10.12.1.1025 - 10.10.2.2.646
state: Oper; Msgs sent/rcvd: 240/240; Downstream
Up Time: 03:52:25
LDP discovery sources:
Vlan10; Src IP addr: 10.10.12.1
holdtime: 15000 ms, hello interval: 5000 ms
Addresses bound to peer LDP Ident:
10.10.12.1
Peer holdtime: 180000 ms; KA interval: 60000 ms
The message above indicates that there is a normal TCP link be-
tween LDPs, with source IP address, destination IP address and
port numbers of the link. When there is no normal TCP link ses-
sion, it will show as follows.

Peer LDP Ident: 10.10.1.1:0; Local LDP Ident 10.10.2.2:0
No TCP connection
state: Non; Msgs sent/rcvd: 0/0; Downstream

After setting up a normal LDP session use the following command
to view the LDP label bindings that have been studied.
