Don't you really mean the USR Routing cards for these hubs? You can
put a Cisco AS5100 in them and they route just like a Cisco 2511.
I beleive the reference was to the NetServer cards, which are a
Livingstone based product, and do *not* do CIDR.
BTW Any BSD4.4 based *NIX (NetBSD, FreeBSD, etc) *does* do CIDR.
