well,
ospf will automatically calcuate the cost by itself, the bigger the
bandwidth line will be chosen.
in order to override it, you need to manaully adjust the cost on each
interface and make
the router believe that both link are each, so they will load balancing the

you can use
ip ospf cost command to change the default cost to the same value for the two lines.
But I suggest you using eigrp which can support unequal lines load balancing.

Hi group
Got a question regarding compression:
Can a Cisco 800, 1720 or 2620 (without AIM) provide ppp (payload)compression for a
2mbit serial line? I dont know if the processor
is able to handle this...
I would appreciate answers from the practical viewpoint.
thanks in advance,

A rotary group creates dialer profiles that can place physical interfaces into
multiple different profiles yes.
Rotary Groups primarily are used to create a Virtual Dialer Interface to dial
out multiple channels.
But I'm talking about dialing in, not out and in the ACRC notes and Cisco
Press
For Cisco 800, it is unavailable, because of 800's max serial speed is 512
Kbps (for non-compress data). But 1720 /2620, i say only MAYBE.

It depends on if your going to use it as a peer with an ISP. I wouldnt
recommend a 1720, but if its stand alone with only static routes to it, you
can live with a 26xx. If you plan on running BGP with full routes or even
partial routes, your router will die.
