I found this on Cisco's website: Q: If custom queuing has been configured, do routing protocol updates such as LSAs for OSPF and broadcasts for RIP and IGRP get queued in the special system queue 0, or do they get queued in the IP queue?
A: In addition to low level keepalives, some protocols whose traffic is originated by the router use queue 0 for their time critical packets. Specifically: ISO IGRP hellos ESIS hellos ISIS hellos DECnet hellos SLARP address resolution EIGRP hellos OSPF hellos Router syslog messages Spanning tree keepalives Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=56159&t=56139 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
