3com 8807 User Guide

In an actual network application, a routing table may contain a large quantity of 
route entries (especially OSPF routes and BGP routes). Generally, the routing 
information is stored in the memory of the switch and the total size of the switch 
memory will not change. When the size of the routing table increases to some 
degree, it may affect the operation of the system. To avoid the occurring of this 
case, you can set the specifications of routing tables and VRFs (VPN routing and 
forwarding instances) in the current system; and the system will inhibit any card 
that below any of the settings from working.
