IPX RIP: SAP Updates Not Propagated by Router (continued)
Possible Problem
Solution
SAP filters have
been
misconfigured.
(continued)
Caution : Because debugging output is assigned high priority in
the CPU process, it can render the system unusable. For this
reason, use debug commands only to troubleshoot specific
problems or during troubleshooting sessions with Cisco
technical support staff. Moreover, it is best to use debug
commands during periods of lower network traffic and fewer
users. Debugging during these periods decreases the likelihood
that increased debug command processing overhead will affect
system use.
If SAP information is forwarded properly by the router, a
SAP filter is causing SAP updates to be dropped by the
router.
4.
To isolate the problem SAP filter, re-enable filters one at a
time until SAP packets are no longer forwarded by the
router.
5.
Change the referenced access list to allow the SAP traffic
that you want to be forwarded to pass through the router.
Make sure that all necessary ports are configured with an
explicit permit statement.
6.
Continue enabling filters one at a time, checking to see that
SAP traffic is still being forwarded properly until you have
verified that all filters are configured properly.
