@chapter Route Map

Route map is a very useful function in zebra.  There is a match and set
statement permitted in a route map.

@example
@group
route-map test permit 10
 match ip address 10
 set local-preference 200
@end group
@end example

This means that if a route matches ip access-list number 10 it's
local-preference value is set to 200.
