In Cisco IOS Release 12.2(4)T, support was added for Cisco MGX 8850 and MGX 8950 switches equipped with a Cisco MGX RPM-PR
card, and the VPI range in the
show mpls atm-ldp bindings and
show mpls ip binding commands was changed to 4095.
In Cisco IOS Release 12.2(8)T, the
debug mpls atm-ldp failure command was introduced.
In Cisco IOS Release 12.0(21)ST, the
mpls ldp neighbor implicit-withdraw command was introduced.
This feature was integrated into Cisco IOS Release 12.0(22)S. The
mpls ldp neighbor targeted-session command and the
interface keyword for the
mpls ldp advertise-labels command were added.
This feature was integrated into Cisco IOS Release 12.0(23)S. Default values for the
mpls ldp discovery
interval keywords were changed.
This feature was integrated into Cisco IOS Release 12.2(13)T.
In Cisco IOS Release 12.4(3), the default MPLS label distribution protocol changed from TDP to LDP. If no protocol is explicitly
configured by the
mpls label protocol command, LDP is the default label distribution protocol. See the
mpls label protocol (global configuration) command for more information.
Also in Cisco IOS Release 12.4(3), LDP configuration commands are saved by using the MPLS form of the command rather than
the tag-switching form. Previously, commands were saved by using the tag-switching form of the command, for backward compatibility.
In Cisco IOS Release 12.4(5), the
vrf-name keyword and argument was added for the
mpls ldp router-id
command to allow you to associate the LDP router ID with a nondefault VRF.
In Cisco IOS XE Release 2.1, this feature was implemented on the Cisco ASR 1000 Series Aggregation Services Router.
The following commands were introduced or modified:
debug mpls atm-ldp failure ,
mpls label protocol (global configuration),
mpls ldp advertise-labels ,
mpls ldp discovery ,
mpls ldp neighbor implicit-withdraw ,
mpls ldp neighbor targeted-session ,
mpls ldp router-id .
