Static Routes
Static routes are used when a dynamic route to a destination cannot be set up
or to specify what the XSR will route to. The XSR sets static routes with the
ip
route
command. Refer to the XSR CLI Reference Guide for more information
and a sample static route configuration.
NOTE
The number of static routes is limited by the size of installed memory.
Routing Priorities
When you have enabled multiple routing protocols or set up static routes and
enabled dynamic routes, the XSR prioritizes these routes in the following
order - 10 is the highest priority. Priorities are not configurable.
