Configuring Route Summarizations

By default, BGP interfaces on the ProCurve Secure Router do not summarize
routes. Currently, this is the only available option.

Setting Administrative Distance for BGP Routes

Your private network should be running an IGP such as RIP or OSPF. The
routes BGP discovers for external sites may be redistributed into this protocol,
or they may be used in conjunction with the IGP routes.
If the router must choose between a BGP route and an identical route
discovered using a different method, it compares the routes' administrative
distances. A route's administrative distance indicates how trusted the source
of a route is. BGP defines different administrative distances for external
routes, routes internal to the AS and local routes.
To set the administrative distance for routes discovered by BGP, enter:
Syntax: distance bgp <administrative distance for external routes> <administrative
distance for routes internal to the AS> <administrative distance for local routes>
The administrative distance should be between 1 and 255. The default for
external routes is 20; for internal routes, 200; and for local routes, 200. For
example, enter:
ProCurve(config-bgp 1)# distance bgp 40 150 220

Altering BGP Intervals

Compared to OSPF and RIP, BGP routers exchange few messages. They only
send routes when they have a new route to advertise or a route to withdraw.
However, you can force the router to send advertisements to a neighbor at
specified intervals. You set the interval for each neighbor from the BGP
neighbor configuration mode context:
Syntax: advertisement-interval <seconds>
The interval can be between 0 and 600. For example:
ProCurve(config-bgp-neighbor)# advertisement-interval 120
