Different passwords on both ends of a PPP CHAP Authentication

[aroehlich]

Hi,

as a default, Cisco IOS expects exactly the same passwords on both Devices that are doing PPP CHAP authentications between them.

What i need is a mutual authentication of both sides using a different password for each authentication. Assuming two routers,R1 and R2, R1 should authenticate R2 using password 1 and R2 should authenticate R1 using password 2.

Is there any way in IOS to do this?

Thank's for your Help in Advance!

Are you running ISDN or point-to-point links?

Hi,

i am running point-to-point links over async serial lines. Does that make a diffenrence? Thank's for your Help!

Yes - over isdn you can use the host name of the devices, or specific passwords in dialer map statements!

over pt-pt links, I'm not sure if you can have anything other than a static password - but I'm not 100%.

You should test it out.
