Chaps,
i came across this recently and was wondering if anyone had seen this before.. we currently have 2 10meg smds(multicast)curcuits spanning the uk each curcuit is terminated at 2 different point`s (seperate HSSI router int`s) in 2 seperate HO`s in the UK.... the HO`s are linked by gig ether-fibre link across the UK. OSPF is the only protocol bieng used (apart from some statics for Backup) after consulting the Cisco Documnetation about HSSI MTU over AAL3 we were advised that an MTU of 4470-9120 compared to the standard of 1500 would greatly increase the performance of our links.... the orignal network desinger set them to this over the last month or so ..these links have been running at 120%..(no good)...so as an experiment the MTU were changed to 1500 for the HSSI int`s and now since then the traffic has decreased to 80%...... anyone seen this before ...and why would the decrease in MTU size cuase less bandwidth to be used ..!!!! anyone TIA steve _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=27673&t=27673 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
