We make heavy use of Microsoft's MSMQ libraries to implement our PGM messaging bus. Unfortunately this implementation of PGM likes to send an awful lot of SPM messages within the PGM streams, each of which have the Router Alert IP option set.
At the moment we're seeing ~10kpps of these packets. Our distribution layer (Cat4500, SupV) is melting under the pressure (90%+ CPU) and Cisco don't seem to be able to give any clear indication as to whether upgrading hardware would help (as these packets all get software routed, simply moving to standard 'faster switching hardware' doesn't help much). Has anyone else run into this problem? If so any ideas on how to mitigate or resolve the issue? At the moment we're potentially looking at having to move all our PGM speakers into a single gigantic world-spanning VLAN to avoid having to route it, but that obviously isn't an ideal solution.
