BGP peculiarity

Hi All,

Can anyone pls explain ....

why is it that in some cases a BGP router would not advertise e-BGP
routes learned from a peer back to the same peer (sticking to the
standard rule on BGP updates).

... while in other cases, BGP will infact advertise the e-BGP routes
learned from a peer back to the same peer (although they do get
rejected by the originating peer because of ASN match ).

I have made these dichotomous BGP observations on a couple of
different scenarios.

Regards
