a quick question for BGP....
R7 and R4 are directly connected and running BGP in between...
R7 has three loopback interfaces who are,,
In order to let R4 see these routes...under R7's bgp configuration i put

network mask
network mask
network mask

But when i do show ip bgp route at R4, these three routes are showing

r4#sho ip route bgp
B [20/0] via, 00:00:17 is variably subnetted, 9 subnets, 5 masks
B [20/0] via, 00:00:17
B [20/0] via, 00:00:17
B [20/0] via, 00:00:17

Why these three routes's mask change from /24 to /16? Both R7 and R4 has ip subnet zero configured...

Thanks a lot!
