Table12-9 ISO CLNS: Poor Performance
Possible Problem
Solution
Multiple
ISO-IGRP
processes are
configured on a
single interface
1.
Use the
show clns interface
exec command to view the
interface configuration. Look for multiple ISO-IGRP
processes that are configured on a single interface.
2.
If multiple ISO-IGRP processes are configured on a single
interface, different Level 2 updates are being sent out
through the same interface.
Multiple Level 2 updates on the same interface can cause
congestion problems, especially if the network is large and links
are flapping outside the damping intervals. Flapping is a routing
problem where an advertised route between two nodes alternates
(flaps) back and forth between two paths due to a network
problem that causes intermittent interface failures.
Remove one of the ISO-IGRP processes from the interface
configuration using the appropriate
no clns router iso-igrp
interface configuration command.
