Summary

Interface

Sub-menu: /mpls traffic-eng interface


Properties:

Property Description
bandwidth (integer[bps]; Default: 0bps) Total bandwidth that can be allocated on an interface by TE tunnels.
blockade-k-factor (integer; Default: 3) Value used to calculate blockade state timeout.
comment (string; Default: ) Short description of the item
disabled (yes | no; Default: yes) Defines whether item is ignored or used. By default VPLS interface is disabled.
down-flood-thresholds (integer[0..100],interer[0..100],...; Default: 15,30,45,60,75,80,85,90,95,97,98,99,100)
igp-flood-period (time; Default: 3m)
interface (string; Default: ) Name of an interface on which to run RSVP.
k-factor (integer; Default: 3) Value used to calculate RSVP timeout. Timeout is calculated using following formula: (K + 0.5)*1.5*R, where K is k-factor, R is refresh-time. Read more >>
refresh-time (time; Default: 30s) Interval in which RSVP Path messages are sent out.
resource-class (integer[0..FFFFFFFF]; Default: 0)
te-metric (integer; Default: 1)
up-flood-thresholds (integer[0..100],interer[0..100],...; Default: 15,30,45,60,75,80,85,90,95,97,98,99,100)
use-udp (yes | no; Default: no) An RSVP implementation generally requires the ability to perform "raw" network I/O, i.e., to send and receive IP datagrams using protocol 46. Some systems may not support raw network I/O, in such cases RSVP messages can be encapsulated in UDP datagrams. Ports 1698 and 1699 will be used.

Property Description
remaining-bw (integer[bps]) Shows currently unallocated bandwidth.

Tunnel Path

Sub-menu: /mpls traffic-eng tunnel-path


Properties:

Property Description
affinity-exclude (integer; Default: ) Do not use the path if resource-class matches any of specified bits.
affinity-include-all (integer; Default: ) Use the path only if resource-class matches all of specified bits.
affinity-include-any (integer; Default: ) Use the path if resource-class matches any of specified bits.
comment (string; Default: ) Short description of the item
disabled (yes | no; Default: yes) Defines whether item is ignored or used. By default VPLS interface is disabled.
holding-priority (integer[0..7]; Default: ) Is used to decide whether this path can be preempted by another path. 0 sets the highest priority.
hops (Address:[strict|loose] [, Address:[strinct|loose]]; Default: ) List of hops that path traverses. Used if use-cspf is not enabled. It is possible to specify strict hop or loose hop:
  • strict - defines that there must not be any other hops between previous hop and "strict" hop (fully specified path).
  • loose - there are acceptable other hops between previous hop and defined hop (not fully specified path).
Read more >>
name (string; Default: ) Descriptive name of tunnel path
record-route (yes | no; Default: ) If enabled, the sender node will receive information about the actual route that the LSP tunnel traverses. Record Route is analogous to a path vector, and hence can be used for loop detection.
reoptimize-interval (time; Default: ) Interval in which tunnel path will be re-optimized. Useful if use-cspf is set to yes.
setup-priority (integer[0..7]; Default: ) Parameter is used to decide whether this path can preempt another path. 0 sets the highest priority.
use-cspf (yes | no; Default: yes) Whether to use CSPF to create dynamic tunnel path.

Monitoring TE Status

Path State

Sub-menu: /mpls traffic-eng path-state


Available read only properties:

Property Description
bandwidth (integer[bps]) Bandwidth required for the path
dst (address:integer) Shows TE path destination address and tunnel ID.
egress (yes | no) Shows if router is egress router of the path
forwarding (yes | no) Shows if router is forwarding router of the path
in-interface (string) Interface on which path message is received.
in-previous-hop (IP) Recorded previous hop
label (integer)
locally-originated (yes | no) Shows if router is ingress router of the path
out-interface (string) Interface through which path message is sent out.
out-label (integer)
out-next-hop (IP)
path-in-explicit-route ()
path-in-record-route (List of IPs) Received recorded routes along the path.
path-out-explicit-route ()
path-out-record-route () List of recorded routes along the path that is sent out to next hop.
resv-bandwidth (integer[bps]) bandwidth that TE path is reserving.
resv-out-record-route ()
sending-path (yes | no) Whether path messages are being sent
sending-resv (yes | no) Whether resv messages are being sent
src (Address:ID) Shows source address and LSP ID number

Resv State

Sub-menu: /mpls traffic-eng resv-state


Available read only properties:

Property Description
active (yes | no) Shows whether reservation is active.
bandwidth (integer[bps]) Bandwidth that RSVP session is allocating.
dst (address:ID) Shows TE destination address and tunnel ID from RSVP session.
egress (yes | no) Shows if router is egress router of the path
interface (string) Shows an interface on which bandwidth is reserved
label (integer)
next-hop ()
non-output (yes | no)
recorded-route (IP[label]) Shows recorded routes and labels along LSP.
shared (yes | no) Whether LSP tunnels can share resources, so that the new LSP tunnel can be set up without having to wait for the old LSP tunnel to be cleared. Read more >>
src (address:ID) Shows TE source address and LSP ID from RSVP session.
