I tried to set up default IP addressing for my dial up users on a 3640 router. I used a pool of three IP addresses for three lines. Things were fine till the first three users connected. A strange thing was happening after that . Users who dialed in were not getting IP addresses from the router. This happened even when all lines were free.
On debugging PPP negotiation, I got the following error -
Se3/0 IPCP: CompressType VJ 15 slots CompressSlotID (0x0206002D0F01)
Se3/0 IPCP: Address 0.0.0.0 (0x030600000000)
Se3/0 IPCP: PrimaryDNS 0.0.0.0 (0x810600000000)
Se3/0 IPCP: PrimaryWINS 0.0.0.0 (0x820600000000)
Se3/0 IPCP: SecondaryDNS 0.0.0.0 (0x830600000000)
Se3/0 IPCP: SecondaryWINS 0.0.0.0 (0x840600000000)
Se3/0 IPCP: Using pool 'default'
Se3/0 IPCP: Cannot satisfy pool request
Se3/0 IPCP: Neither side knows remote address
On checking the IP pool when only one line was active, I got the message that all three IP addresses were in use. I tried using a block of 30 addresses for the pool, and things are working fine.
I had assumed that I need only three IP addresses in a pool to serve three lines. But things are not working out that way.
Any ideas ?

I do not have a CCO login to open a TAC case. Could you please try to resolve this issue for me ?

Hi.
Can you post your config?
Remote access is not my specialty, but I can try...

Somehow router still thinks that the connection on those three lines are still active and ip addresses are still in use. Type "sh users" and see is the router still see the users connected. Also "sh ip route" may report route will be there..Also post the config too.Thx..Tejal

As already mentioned, I have only three lines connected to my router. Any help will be appreciated very much. Thanks :-)

Pls. parse the config of pool and dial portion, you sure router is sending one of those IP addresses out of the pool? IPCP should not be 0.0.0.0
