Configuring IP Services
C-16 117356-A Rev. A
Parameter: Preference
Path: Configuration Manager > Protocols > IP > Route Filters > BGP3 > Import
Filters
Default: 1
Options: 1 to 16
Function: Assigns a weighted preference value to a route included in the routing tables. If
confronted with multiple routes to the same destination, the router, by default,
grants preference to routes in the following order: direct, OSPF internal,
BGP-3, static, OSPF, external, and RIP. If Intra-AS IBGP routing is used, then
any other route source is preferred over a BGP-3 route.
Instructions: If this hierarchy is acceptable, accept the default value 1 for preference. If you
want to grant preference to this BGP-3-derived route, assign a new preference
value in the range of 1 to 16 (the greater the number, the higher the preference).
The default preference for static routes is 16, but may be set to any value from
1 to 16. If you want to grant a BGP-3-derived route preference over a static
route, make sure the preference you assign to the BGP-3-derived route exceeds
the preference value of the static route you want it to override. Either accept the
default value, 1, or enter a new value. Routes for all networks (0.0.0.0/0.0.0.0)
should have the lowest preference. Routes for the most specific networks
(longest address and mask) should have the highest preference.
