show mpls ldp fec prefix A.B.C.D/y
The prefix option is introduced to the show mpls ldp fec command. The show mpls ldp fec
prefix command displays the total number of Layer 3 FECs.The output of show mpls ldp fec prefix
command is modified to indicate the upstream mappings, which are filtered because of the action
of peer or global outbound FEC filter, as (f) instead of the label. (f) indicates that the FEC is filtered
and no label mapping is advertised to the given LDP peer.
Syntax show mpls ldp fec [prefix [A.B.C.D/y/filtered/prefix-filter]][summary][vc vc_Id]
Parameters prefix
The prefix option displays the total number of Layer FECs specified by the A.B.C.D, filtered, or
prefix-filter variable.
summary
The summary option displays the summary configuration information.
vc
The vc option displays the VC FEC configuration information specified by the vc_Id variable.
Command
modes
This command operates in all modes.
Usage guidelines Use the command to indicate the upstream mappings, which are filtered because of the action of
peer or global outbound FEC filter, as (f) instead of the label. (f) indicates that the FEC is filtered
and no label mapping is advertised to the given LDP peer.
Command
output
The show mpls ldp fec prefix [A.B.C.D/y] command displays the following information.
Command output Description
FEC_CB Memory address of the FEC CB.
idx A monotonically increasing number assigned to each FEC in the LDP internal FEC tree.
type FEC type – Prefix FEC is type 2 and Host Address is assigned type 3.
pend_notif Any notification pending on this FEC.
State State of the FEC which indicates the FEC advertised to any LDP session (state equal to
“current”). When it has no session, it is either called “cur_no_sess” (currently no
session) for local FECs or is marked “retained” for non-local.
Ingr Whether the FEC is an ingress FEC.
Egr Whether the FEC is an egress FEC.
UM Dist Specifies when Upstream Mapping Distribution is complete.
Prefix The IP Prefix associated with the host address or the prefix FEC type.
next_hop For an ingress FEC, this mentions the next-hop IP address. When LDP selects its
outgoing interface as an RSVP tunnel, the ‘next_hop’ field displays the RSVP tunnel
destination address.
out_if For an ingress FEC, this mentions the output interface to reach to the Next-hop. When
applicable, the ‘Out-Intf’ field displays a VE interface specified by the vid variable.
