LDP Inbound-FEC filtering
2
The prefix list parameter specifies the prefixes.
The in keyword specifies inbound-fec-filter configuration.
Use the [no] form of this command to remove the LDP inbound FEC filter.
Modifying prefix-list after setting it in the filter-inbound-FEC
When the prefix-list referenced by the LDP inbound-FEC filter is configured or changes, all the
existing in-bound FECs and received later are subject to the changed prefix-list.
NOTE
There is a configurable delay between changing the prefix-list and the changed prefix-list taking
effect on LDP FEC-filter configuration.
Brocade(config)# ip prefix-list list-abc permit 10.20.20.0/24
Brocade(config)# router mpls
Brocade(config-mpls)# ldp
Brocade(config-mpls-ldp)# filter-fec list-abc in
Brocade(config-mpls)# exit
Brocade(config)# exit
Brocade(config)# ip prefix-list list-abc permit 10.21.21.21/24
Syntax: [no] filter-fec prefix list in
The prefix list parameter specifies the prefixes.
The in keyword specifies inbound-fec-filter configuration.
Displaying FEC information
The show mpls ldp command displays the inbound FEC-filter configuration. When applying the
prefix-list on LDP filter-FEC before creating it, it displays as “unbound”.
Brocade# show mpls ldp

The inbound filter-FEC is set to the prefix-list named list-xyz when list-xyz is not created in the
following example.
