Generic Commands
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.
The no form of this command disables the statistics in the egress data path and removes the
accounting policy association from the LDP FEC.
Default
none
