does RIP v2 really support VLSM

Hi all,

Last week I stuck on a problem in RIP v2. My scenario was very simple. I have two router connected back to back R1-R2, the ip addressing is like below:

R1 s0/0 12.12.12.1/7 lo0 111.111.111.111/8

R2 s0/0 12.12.12.2/7 lo0 112.112.112.112/8

I could not get the rip route for loopback!!!.

When i change the encapsulation from HDLC to PPP wow!!! Strange I got the RIP route.

I could not understand this behavior of RIP?

Regards,
