Applications Perform Poorly
Cause 1 —Network-layer packets are being retransmitted because there
is a software error or because two important timers are misconfigured in
NIASCFG. The important timers are the Minimum Non-Broadcast LSP
Transmission Interval timer (which indicates the amount of time before
an LSP is retransmitted when there is no acknowledging Partial Sequence
Number Packet [PSNP]) and the Partial SNP Interval timer (parameter
path: Select Configure NIAS > Protocols and Routing > Protocols >
Expert Configuration Options > NLSP Convergence Rate Configuration).
The latter timer should be set to a value much smaller than the value set
for the former timer because it acknowledges LSPs; if it is set too high,
the LSP transmitter responds as if the LSP is lost and retransmits the LSP.
If the problem persists after you reconfigure the timers, call technical
support.
Cause 2 —Many changes are occurring in your network because there is
too much RIP activity in your network.
Migrate more of your network to NLSP.
Cause 3 —Some systems are sending too many updates.
If possible, migrate more of your network to NLSP.
If you cannot migrate more of your network to NLSP, find the
boundary routers (those that are importing RIP) by looking at the
NLSP LANs window. Increase the Maximum LSP Generation
Interval option on these systems.
You are experiencing poor application performance on systems in your
network.
Cause 1 —Suboptimal path has been selected by NLSP.
Check the end-to-end path of the connection and make sure that the links
that you thought would be chosen are being used to forward data. In an
NLSP area, look at the Potential Paths window by loading IPXCON
(parameter path: Select Forwarding > a specific destination). Outside an
NLSP area, perform the procedure described in
Problems (Duplicate ID or Network Number)" on page
If you find an incorrect path caused by RIP, then you can increase the RIP
cost by manually changing the cost of the RIP link. Refer to "Configuring
RIP and SAP" for information about how to do this.
