.. note::
IS-IS-TE supports RFC 5305 (base TE), RFC 6119 (IPv6) and RFC 7810 / 8570
(Extended Metric) with or without Multi-Topology. All Traffic Engineering
information are stored in a database formally named TED. However, best
acccuracy is provided without Multi-Topology due to inconsistency of Traffic
Engineering Advertisement of 3rd party commercial routers when MT is enabled.
At this time, FRR offers partial support for some of the routing protocol
extensions that can be used with MPLS-TE. FRR does not currently support a
complete RSVP-TE solution.
