Hi,

I'm running  BGP test-cases documented by University Of New Hampshire. One of the \
test cases is related to the attribute ATOMIC_AGGREGATE. The test-case is :

The Router Under Test [RUT] is configured with " aggregate-address 192.0.0.0/8 "  and \
the RUT receives overlapping routes  like 192.0.0.0/8 and 192.1.0.0/16  from two \
different external BGP peers

Then, the expected result should be  :

When RUT receives overlapping routes  then it should  either only install the \
aggregate i.e 192.0.0.0/8 or install the two component routes i.e \
192.0.0.0/8,192.1.0.0/16 .

But in my case the RUT installs the route to 192.1.0.0/16 but not 192.0.0.0/8 or the \
aggregate.

Moreover , the test-results published in
 http://www.quagga.net/docs/unh/BGP_Report_Sun_10-06-04.pdf also reports the same.

Any clues to fix this issue and pointers to the issues uncovered in the document  \
BGP_Report_Sun_10-06-04.pdf.

Thanks In Advance,
Chaitanya
