Hi experts
I am facing this in dynamip with c3640-jk9o3s-mz.124-16.bin IOS
here is my scenario
R4(S1/1)---PPP----(s1/1)R5
R4
int s1/0
ip add 163.1.45.4 255.255.255.0
encap ppp
no sh
R5
int s1/0
ip add 163.1.45.5 255.255.255.0
encap ppp
no sh
---------------
R4
Rack1R4(config)#do sh ip rou con
163.1.0.0/16 is variably subnetted, 6 subnets, 2 masks
C 163.1.45.5/32 is directly connected, Serial1/1
C 163.1.45.0/24 is directly connected, Serial1/1
C 163.1.0.0/24 is directly connected, Serial1/0
R5
Rack1R5(config-if)#do sh ip rou con
163.1.0.0/16 is variably subnetted, 6 subnets, 2 masks
C 163.1.45.4/32 is directly connected, Serial1/1
C 163.1.45.0/24 is directly connected, Serial1/1
C 163.1.0.0/24 is directly connected, Serial1/0

Why the interface serial 1/1 shows two mask?
If i changed the encapsulation ppp to default hdlc then it shows single mask.
Would you please anyone explain me?
Advance thanks
Li
