4.2.2 Link Parameters Commands

Interface Command: link-params

Interface Command: no link-param

Enter into the link parameters sub node. At least ’enable’ must be set to activate the link parameters, and consequently Traffic Engineering on this interface. MPLS-TE must be enable at the OSPF (OSPF Traffic Engineering) or ISIS (ISIS Traffic Engineering) router level in complement to this. Disable link parameters for this interface.

Under link parameter statement, the following commands set the different TE values:

link-params: enable

Enable link parameters for this interface.

link-params: metric <0-4294967295>

link-params: max-bw bandwidth

link-params: max-rsv-bw bandwidth

link-params: unrsv-bw <0-7> bandwidth

link-params: admin-grp bandwidth

These commands specifies the Traffic Engineering parameters of the interface in conformity to RFC3630 (OSPF) or RFC5305 (ISIS). There are respectively the TE Metric (different from the OSPF or ISIS metric), Maximum Bandwidth (interface speed by default), Maximum Reservable Bandwidth, Unreserved Bandwidth for each 0-7 priority and Admin Group (ISIS) or Resource Class/Color (OSPF).

Note that bandwidth are specified in IEEE floating point format and express in Bytes/second.

link-param: delay <0-16777215> [min <0-16777215> | max <0-16777215>]

link-param: delay-variation <0-16777215>

link-param: packet-loss percentage

link-param: res-bw bandwidth

link-param: ava-bw bandwidth

link-param: use-bw bandwidth

These command specifies additionnal Traffic Engineering parameters of the interface in conformity to draft-ietf-ospf-te-metrics-extension-05.txt and draft-ietf-isis-te-metrics-extension-03.txt. There are respectively the delay, jitter, loss, available bandwidth, reservable bandwidth and utilized bandwidth.

Note that bandwidth are specified in IEEE floating point format and express in Bytes/second. Delays and delay variation are express in micro-second (µs). Loss is specified in percentage ranging from 0 to 50.331642% by step of 0.000003.

link-param: neighbor <A.B.C.D> as <0-65535>

link-param: no neighbor

Specifies the remote ASBR IP address and Autonomous System (AS) number for InterASv2 link in OSPF (RFC5392). Note that this option is not yet supported for ISIS (RFC5316).
