An SSR’s export routing policies control which routes the SSR advertises to other systems. 
Route exportation is controlled by both destination and source. Export policies specify the 
destinations to which the router will export, the sources from which the router will export, 
and the types of routes that will be exported, which can be either specific routes or all the 
routes a router has learned.

Suppose the SSR is attached to RIP and OSPF routers as shown in the following figure. 
Also suppose that RIP router 5 has learned all of the routes attached to RIP router 4. You 
could configure an export policy that directs the SSR do the following:

•

Export all the routes of OSPF router 3 to RIP router 6.

•

Export to RIP router 2, all of the routes directly attached to RIP router 5 but only some 
of the routes RIP router 5 has learned from RIP router 4.
