prefix-exclude
Syntax prefix-exclude policy-name [policy-name...(up to 5 max)]
no prefix-exclude
Context config>router>ldp>aggregate-prefix-match
Description This command specifies the policy name containing the prefixes to be excluded from the aggregate
prefix match procedures. In this case, LDP will perform an exact match of a specific FEC element
prefix as opposed to a longest match of one or more LDP FEC element prefixes, against this prefix
when it receives a FEC-label binding or when a change to this prefix occurs in the routing table.
The no form of this command removes all policies from the configuration.
Default no prefix-exclude.
egress-statistics
Syntax egress-statistics
Context config>router>ldp
Description This command provides the context for the user to enter the LDP FEC prefix for the purpose of
enabling egress data path statistics at the ingress LER for this FEC.
Default none
fec-prefix
Syntax [no] fec-prefix ip-prefix[/mask]
Context config>router>ldp>egr-stats
Description This command configures statistics in the egress data path at the ingress LER or LSR for an LDP
FEC. The user must execute the no shutdown command for this command to effectively enable
statistics. The egress data path counters will be updated for both originating and transit packets.
Originating packets may be service packets or IP user and control packets forwarded over the LDP
LSP when used as an IGP shortcut. Transit packets of the FEC which are label switched on this node.
When ECMP is enabled and multiple paths exist for a FEC, the same set of counters are updated for
each packet forwarded over any of the NHLFEs associated with this FEC and for as long as this FEC
is active.
The statistics can be enabled on prefix FECs imported from both LDP neighbors and T-LDP
neighbors (LDP over RSVP).Only /32 FEC prefixes are accepted. Service FECs, i.e., FEC 128 and
FEC 129 are not valid. LDP FEC egress statistics are not collected at the Penultimate-Popping Hop
(PHP) node for a LDP FEC using an implicit null label.
The no form of this command disables the statistics in the egress data path and removes the
accounting policy association from the LDP FEC.
