BGP aggregate address and redistribute commands

[Kashish_Patel]

We have "aggregate address" as well as "redistribute ospf" commands configured under "router bgp". This is how I understand these statements:

First, route will be redistributed from ospf to bgp and while advertising out to the other BGP neighbor, that route will be summarized if it's already being covered by aggregate address statement. Is this correct?

Thanks.

Hi,

redistribute OSPF gets the OSPF routes into the BGP table and then aggregate address summarizes some routes that are in the BGP table( but not necessarily encompassing the redistributed routes) and advertises the summary and the component routes by default as well as other prefixes.

Regards.
