Displaying the MPLS forwarding information
The show mpls forwarding command is introduced to display MPLS forwarding information. The
out-intf field in the output of the show mpls forwarding command displays whether an
interface/port is either an Ethernet port or a POS port. For example, Ethernet port 3 on slot 2 is
displayed as e2/3.
To display MPLS forwarding information, enter the show mpls forwarding command as shown in the
example below.
Brocade# show mpls forwarding
Total number of MPLS forwarding entries: 2
Dest-prefix In-lbl In-intf Out-lbl Out-intf Sig Next-hop
1 10.140.140.4/32 3 e1/2 R 10.20.20.2
2 10.140.140.4/32 1024 e1/10 R 10.20.20.2 DET
Syntax: show mpls forwarding [ip_prefix_addr/mask_len [longer] | ip_prefix_addr /ip_mask
[longer]| p2mp | p2p ]
where:
• ip_prefix_addr means display the route to the specified IP address.
• mask_len is the number of bits in the mask.
• longer means that when an IP address has been specified, display only the routes that match
that IP address.
• ip_mask is the bytes of a network mask or, for CIDR format, the number of bits in the network
mask.
• p2mp option displays all P2MP forwarding entries for the specified destination or a specified
in-label value or a P2MP-ID.
• p2p option displays all P2P forwarding entries for the specified destination or a specified
in-label value.
Label The MPLS label received from the downstream router.
sig The signal protocol type associated with the label. Possible values are:
•
L – LDP
•
R – RSVP
Usage The number of LSPs that are either currently using or configured to use the path. For example,
When an LSP named “to_sqa” has primary and secondary paths and both paths are
configured to use the same MPLS path “path_to_sqa,” then the usage count for “path_to_sqa”
would be two (when no other LSP in the system is configured to use “path_to_sqa”).”

dest-prefix The destination FEC of the LSP.
in-lbl The incoming segment or upstream label for the LSP. A value of 0 indicates the absence of the
segment.
