I'm doing a small lab. I need to make DHCP pools for VLAN's on Router1 and configure DHCP-relay agent on Router1 so PC's from VLAN 300 and 400 could recieve addresses from pools in Router0.
I made the pools, but I'm really confused about configuring Router1. I rellay hope someone would help me out!
The file I attached is renamed .pkt. I'm using Packet Tracer version 6.3. Thanks for you help!
FA0/0.100, FA0/0.200, FA0/1.300 & FA0/0.400 can be whatever address you want in their respective subnet, just make sure to include the helper address on each interface that utilized R0 for DHCP.
Note:- if all you clients are only internal from rtr1 then you don't require any dhcp relay on rtr if that rtr is supplying dhcp.
The problem you've got isnt the Dhcp allocation its the topology setup, What is Rtr 0 suppose to be doing?
You have to physical interfaces on rtr1 which can be both configured as sub-interface for the vlans ( "router on a stick" scenario) - however whats the addressing for rtr 0 as this will require one.
Can you elaborate your end goal for this please.
please find attached the working config. I am not sure what the requirement is, but some major changes were needed. I deleted the subinterfaces for Vlan 300 and Vlan 400 on Router0 and on FastEthernet0/0 of Router1, since that couldn't work: you were trying to configure the same subnet on three interfaces.
I added a subinterface for Vlan 100 and Vlan 200 on Router 1, and added IP heloer addresses on the Vlan 300 and Vlan 400 subinterfaces of Router1.
I also added static routes on Router0 pointing to Router1. And last but not least, all switchports were configured with 'spanning-tree portfast'.
When you open the file, give it a minute or two to converge. Then try to release/renew the IP addresses.
