Displaying LDP information

Displaying the contents of the LDP database
The show mpls ldp database command has been enhanced to have a filter for peer address. The
peer address is the IPv4 address of the LDP Peer of an LDP Session. Output of the command with
the peer address filter displays the database details only for a single specified peer.
The user can display the contents of the LSRs LDP Label Information Base. This database contains
all the labels it has learned from each of its LSR peers, as well as all of the labels it has sent to its
LDP peers.

Syntax: show mpls ldp database [peer-ip-address]
For each LDP session, the show mpls ldp database command displays the following information
Metric Metric value for the tunnel.
Next-hop index Index of the next hop used for this tunnel.
TABLE 50 Output from the show mpls ldp database command
This field... Displays...
Session The LDP identifiers of this LSR and its peer.
Downstream
label database Information about labels received from the LDP peer
Upstream label
database Information about labels distributed by this LSR to the LDP peer. The device sends the same
label for a given prefix to all of its upstream peers. In the example above, label 1028 is
mapped to prefix 10.14.14.14/32. This device sends this label mapping to each of its
upstream peers.
Label The label value received from or distributed to LDP peers. It also displays the label values for
VC FECs received from downstream LDP peers or advertised to up stream LDP peers.
