Chapter 9: Configuring Unicast Routing on the SSR

138

CoreWatch User’s Manual

the SSR's subnetwork. You could also configure the SSR to not accept RIP data from the 
subnetwork but to accept RIP packets from the other RIP router.

In the IP environment, RIP bases routing on a hop count. RIP only supports routes that 
have 0 to 15 hops. You can configure the SSR to adjust hop counts. Doing so lets you 
control which routes the SSR prefers to use to send or receive data when it is 
communicating with another RIP router.

What Is Preference?

Preference is the value the SSR uses to determine the preference of routes from one 
protocol or peer over another. You can set preference based on one network interface over 
another, from one protocol over another, or from one remote gateway over another. A 
default preference is assigned to each source from which the SSR receives routes. 
Preference values range from 0 to 255 with the lowest number indicating the most 
preferred route. 

Preference may not be used to control the selection of routes within RIP or another 
Interior Gateway Protocol (IGP) because that is accomplished automatically by the 
protocol’s metric.

Preference may be used to select routes from an Exterior Gateway Protocol (EGP), such as 
the Border Gateway Protocol (BGP), learned from different peers or autonomous systems. 

As shown in the following table you can set preference in several places. The table 
identifies each item on which you can set preference and identifies the default preference 
value of each item. For details on setting the preference of static routes, see 

“Defining 

Static Route Entries” on page 135

. For details on setting the preference of RIP routes, see 

“Setting RIP Global Parameters” on page 139

. For details on setting the preference of all 

other items, see the 

SmartSwitch Router Command Line Interface Reference Manual
