Is this a Packet Tracer bug?

Please forgive me for being a newbie. I'm just now starting to work on static routing and im having some trouble understanding it. I did a 'show ip route' on one of my routers in Packet Tracer and i got this

R2#show ip route

<Text removed>

10.0.0.0/24 is subnetted, 1 subnets
C 10.50.0.0 is directly connected, FastEthernet0/0
172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 172.16.0.0/30 is directly connected, Serial3/0
C 172.16.0.1/32 is directly connected, Serial2/0
C 172.16.1.0/30 is directly connected, Serial2/0
S 192.168.1.0/24 [1/0] via 172.16.0.1

So is it normal to have 2 networks connected to serial 2/0?

The 2811's we have in class do this. The /32 should be the actual IP address of the interface, so it's technically not two networks.

thanks for the help guys. I closed Packet Tracer without saving the project. Ill try to build it from ground up again and do a show ip int brief.

That /32 I believe is the result of using PPP encapsulation. I'm not too sure into the details, but I believe thats why It's in the routing table.

Yep.

Soooo true!
A good refresh and why the router would need a /32 route to a remote ppp dialer?
I guess it was for the pots dialing with 56K modems, but i would be thankful to understand why a route was needed in such case? Was it to isolate something anyhow?

I did a little googling and found this, and a few other blogs saying basically the same thing.
