Chapter 6 Route Capacity Configuration
Note:
When running a routing protocol, the Ethernet switch also functions as a router. The
words “router” and the router icons covered in the following text represent routers in
common sense and Ethernet switches running a routing protocol.
Among S3600 series, only S3600-EI series switches support route capacity
configuration.
6.1 Route Capacity Configuration Overview
6.1.1 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 S3600 series 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.
Caution:
Note that, normally, the default system configuration meets the requirements. To
avoid decreasing system stability and availability due to improper configuration, it is
not recommended to modify the configuration yourself.
6.1.2 Route Capacity Limitation on the S3600 Series
Huge routing tables are usually caused by OSPF routes. Therefore, the route capacity
limitation implemented by an S3600 Ethernet switch applies to OSPF routes only but
not to static and RIP routes.
