Hi Ujjwal,
I reproduced your issue, I think the entry comes from the static route:
ip route 100.100.0.0 255.255.0.0 Null0
This gets into the RIP database, do a "show ip rip database" and I think you
will see an entry like this:
100.100.0.0/16 directly connected, Null0
Which, unless filtered, will be redistributed into BGP.
Cheers,
Ato.
