Route Capacity Configuration Overview
Introduction
In practical networking applications, there are a large number of routes, especially OSPF routes, in the
routing table. Normally, routing information is stored in the memory of the switch. While the size of the
routing table increases, the total memory of the switch remains unchanged unless the hardware is
upgraded. However, upgrading may not always solve the problem.
To solve this problem, the switches provide a mechanism to control the size of the routing table; that is,
monitoring the free memory in the system to determine whether to add new routes to the routing table
and whether to keep the connection of a routing protocol.
Normally, the default configuration of the system can meet the requirements. To avoid decreasing
system stability and availability due to improper configuration, it is not recommended to modify the
configuration.
Route Capacity Limitation
Huge routing tables are usually caused by OSPF route entries. Therefore, the route capacity limitation
of a switch applies only to OSPF routes, instead of static routes and RIP routes. The route capacity
limitation is implemented by controlling the size of the free memory of the switch.
