The aggregate should have been 10.64.192.0/20 or above, rather 19.
with a mask of 19 it includes only networks 10.64.192.0 to 10.64.199.0.
thanks

Subject: BGP aggregate addresses

Hi
group,

My understanding of BGP aggregate addresses is that it will advertise
the aggregate if there is at least one network within the aggregate in
the BGP
table. However, I have the following problem:

I am aggregating 10.64.192.0/19
from an iBGP peer which is a route
reflector client. It has loopbacks within
this range, eg
10.64.200.1/24, but the aggregate only gets advertised if
10.64.192.0/24 is in the BGP table. Is this normal behaviour?

Thanks,
Patrick
