Your configuration seems okay to me. Try to renegotiate ppp between the two devices. That will trigger ipcp, and peer address assignment. Shut down and unshut the dialer interface on R1. I presume you can ping the dhcp server.

Subject: PPP negotiated address...
Hi all
I am trying to configure PPP over ISDN to get the IP from a DHCP server.
This are my configs:
On R1...
interface Dialer1
ip address negotiated
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer string 5552026
dialer persistent
end
On R2...
interface Dialer1
ip address 1.1.1.2 255.255.255.0
encapsulation ppp
dialer pool 1
dialer string 5552024
peer default ip address dhcp
end
ip dhcp-server 10.10.10.5
On R5 (directly connected to R2 through Ethernet segment):
no ip dhcp conflict logging
ip dhcp excluded-address 1.1.1.2
!
ip dhcp pool ISDN
network 1.1.1.0 255.255.255.0
!
By some reason It is not working. R1 does not get and IP address, and
"show ip dhcp server statistics" does not reveal any dhcp packet
exchange. Any thoughts? I guess I missing something, but I don't know
what...
Thank you in advance
Javi
