This document describes the Route Switch Processor (RSP2), the default system processor for the
Cisco 7505, Cisco 7507 and Cisco 7513 routers.
We strongly recommend that you do not use the RSP2 in the Cisco 7507-MX, and Cisco 7513-MX
Caution
routers. The Cisco 7507-MX and Cisco 7513-MX routers ship by default with an RSP8.
The RSP2 supports the high system availability (HSA) feature, which allows two RSP2s, or an RSP4/4+
and an RSP2, to be used in a Cisco 7507 and Cisco 7513 routers. See the
Availability" section on page 23
The RSP2 also supports high availability (HA), a series of features that operates similarly to HSA, but
which further minimizes system downtime. (HSA is the system default.) For more information on HA,
see the
With HA or HSA enabled, the RSP2 supports online insertion and removal (OIR).

    Ensuring That Both RSPs Contain the Same Configuration File With the simple hardware backup and software error protection implementation methods, you always want your active and standby configuration files to match. To ensure that they match, turn on automatic synchronization. In automatic synchronization mode, the active copies its startup configuration to the standby’s startup configuration when you issue a copy command that specifies the active’s startup configuration (nvram:startup-config) as the target.
