Traffic Engineering
###################
Traffic Engineering (TE) is possibility to send traffic from node to node using
alternative path.
Common link parameters
----------------------
Traffic Engineering parameters are used for both IS-IS and OSPF (not supported yet).
.. cfgcmd:: set protocols traffic-engineering admin-group <admin-group-name> bit-position <bit-position-value>
Create Administrative group and assosiate bit position with it. These groups can be
used in the following commands.
<bit-position-value> can have value 0-31. There cannot be two groups with same bit position.
.. cfgcmd:: set protocols traffic-engineering interface <ifname> admin-group <admin-group-name>
Set administrative group for interface <ifname>. Multiple values can be provided.
.. cfgcmd:: set protocols traffic-engineering interface <ifname> max-bandwidth <max-bandwidth-value-mbps>
Set maximum bandwidth for interface <ifname>. Value given in Mbits per second.
.. cfgcmd:: set protocols traffic-engineering interface <ifname> max-reservable-bandwidth <max-reservable-bandwidth-value-mbps>
Set maximum reservable bandwidth for interface <ifname>. Value given in Mbits per second.
IS-IS TE Configuration
----------------------
Traffic Engineering (TE) can be enabled and exported for IS-IS
using the following commands:
.. cfgcmd:: set protocols isis traffic-engineering enable
Enable Traffic Engineering for IS-IS.
.. cfgcmd:: set protocols isis traffic-engineering export
Export Traffic Engineering data to neighbors.
.. cfgcmd:: set protocols isis traffic-engineering address <ipv4-address>
Configure IPv4 address for MPLS-TE.
