l2tp + radius questions

hi all,

i'm setting up an l2tp connection - ce router, LAC and LNS as per :- http://www.cisco.com/en/US/products/sw/secursw/ps4911/products_configuration_example09186a00801175d1.shtml

I managed to get the connection works using the PAP for ppp authentication but somehow confused with the infos from the said doc.

It says :-

rtp.cisco.com Password = "cisco"

Service-Type = Outbound-User,

cisco-avpair = "vpdn:tunnel-id=DEFGH",

cisco-avpair = "vpdn:tunnel-type=l2tp",

cisco-avpair = "vpdn:ip-addresses=10.31.1.9",

cisco-avpair = "vpdn:l2tp-tunnel-password=ABCDE"

My qeustion is, where does the password "cisco" defined in the RAS (LAC). Is it a default value ? Can it be changed ?

I also failed at L2TP tunnel establishment stage when using CHAP for ppp authentication. From RADIUS debug (Free Radius), it looks like RAS (LAC) is supplying a PAP style attribute "User password" instead of "CHAP password" although configured for CHAP.

Appreciate any input.

thanks,

Re: l2tp + radius questions

The command 'radius-server key cisco' is probably configuring the password for this purpose.
