traffic-eng advertisements

Tuning Adjacencies for IS-IS

This task explains how to enable logging of adjacency state changes, alter the timers for IS-IS adjacency
packets, and display various aspects of adjacency state. Tuning your IS-IS adjacencies increases network
stability when links are congested. This task is optional.
For point-to-point links, IS-IS sends only a single hello for Level 1 and Level 2, which means that the level
modifiers are meaningless on point-to-point links. To modify hello parameters for a point-to-point interface,
omit the specification of the level options.
The options configurable in the interface submode apply only to that interface. By default, the values are
applied to both Level 1 and Level 2.
Purpose
Specifies that the MPLS TE router identifier for the node
is the given IP address or an IP address associated with
the given interface.
Configures a router to generate and accept only wide link
metrics in the Level 1 area.
(Optional) Displays MPLS TE tunnel information.
(Optional) Displays a log of MPLS TE IS-IS adjacency
changes.
(Optional) Displays the latest flooded record from MPLS
TE.
