Physical Interface Configuration Commands

All commands in this section begin with mpls traffic-eng and are configured on the physical interface.

Command	Modifiers	Default	Use
…administrative-weight	0-4294967295	Admin weight takes the same value as the IGP cost.	Use this to engender delay-sensitive metrics.
…attribute-flags	0x0-0xFFFFFFFF	0x0	Sets the attribute flags on an interface.
…backup-path	tunnel-name	Off	Sets the tunnel inter-face that protects this physical interface, for FRR link protection.
…flooding thresholds	{down | up} 0-100 …	Up: 15 30 45 60 75 80 85 90 95 96 97 98 99 100 Down: 100 99 98 97 96 95 90 85 80 75 60 45 30 15	Bandwidth threshold that, when crossed, triggers IGP flooding of the TE information about this link.
…tunnels	None	Off	Enables MPLS TE on an interface.

In addition, three particularly useful MPLS commands are configured on a physical interface but are not options of mpls traffic-eng. They are as follows.

Command	Modifiers	Default	Use
mpls accounting experimental	{input | output}	Neither	Counts MPLS packets by EXP, in either the in (Rx) or out (Tx) direction—or both, if you configure them both. You can view these counts with show interface interface mpls-exp.
mpls netflow egress	None	Off	Netflow normally works on packets that have come into the router as IP. This command allows you to account for packets that come into the router as MPLS, but have their label stack removed and leave as IP.
ip rsvp bandwidth	[1-10000000 reservable BW [sub-pool 1-10000000 reservable BW]]	Off	Configures the amount of reservable bandwidth on an interface; see Chapter 3, "Information Distribution."
