is this a IOS bug?

[samsam_wang]

sometimes, I am confused about this.

my 2514

I give 16.203.24.1/30 to s1, when I "sh ip route", it shows:

*******

C 16.203.24.0/30 is directly connected, Serial 1

*******

after I changed the IP to 16.203.25.1/24, when I "sh ip route", it shows:

*******

C 16.203.24.0/30 is directly connected, Serial 1

C 16.203.25.0/24 is directly connected, Serial 1

*******

there are two IPs connected with the interface.

but for "sh inter s 1", only ONE ip there.

who would like tell me what that is?

Thanks.
