We don't filter it yet, but Princeton has some pretty good pages with good
justifications for blocking (or getting users to disable these protocols).
For example:
http://www.net.princeton.edu/filters/ssdp.html
The following link lays out the other protocols they filter.
We filter mdns, slp, upnp, ssdp, etc. Many of these are ttl=1 multicasts
that chew up cpu time on our routers.
On the aruba system we have broadcast-filter arp and all configured since
we have approx an ipv4 /18's worth of clients chattering away.
