sending BGP partial routes

[grunky]

I'm in the process of setting up BGP to a customer that is downstream from us. When asked if the customer wants BGP they said - yes - BGP with partial routes not full.

I know how to setup a BGP peering relationship but not sending partial routes. I'm assuming sending partial means that the upstream BGP peer would send large aggregate addresses instead of its ful BGP RIB.

Would anyone have helpful links on setting up BGP peers w/ partial routes?

Typically, what customers mean when they say partials is the routes which originate within your AS, the AS' of your customers, and the default route. So, the two filters you could use would be:

^$ is only the routes originating within your AS.

^[1-9]*$ is the routes originating within your AS, and those which originate within an AS you are directly peered with.

You would use either of these as an AS Path filter.
