Hi
Might be this one is discussed in this forum before as I see one of
archieve on the same topic ; but somehow I cannot get this working .
Will be great if someone help me out with this :
PLease note that connectivity is not a issue in this as my DHCP server
at R1 is able to reach the 139.1.45.5 address .
R4(s0/0/1) ========139.1.45.5 (s0/0/1) R5 139.1.15.5============FR
==========139.1.15.1 R1
R1 has connectivity to 139.1.45.5 .
R4 tries to get IP address via IPCP negotiation from R5.
R5 forwards this to DHCP server at R1.
R4
interface Serial0/0/1
description "to R5"
ip address negotiated
ip rip advertise 3
encapsulation ppp
end
R5
interface Serial0/0/1
description " To R4"
ip address 139.1.45.5 255.255.255.0
ip rip advertise 3
encapsulation ppp
peer default ip address dhcp
clock rate 2000000
end
!
R1
Rack1R1(config-if)#do sh run | inc dhcp
ip dhcp excluded-address 139.1.45.1 139.1.45.3
ip dhcp excluded-address 139.1.45.5 139.1.45.255
ip dhcp pool R4
Connectivity is NOT a problem as DHCP server R1 is able to reach 139.1.45.5 .
I am getting following debugs indicating some mismatch :
