I have a problem. I'm doing a small lab for the courses.
I need to create 4 DHCP pools for 4 VLAN's on Router0. And then to configure DHCP-relay agent on Router1, so PC's in VLAN 300 and 400 could recieve IP addresses from DHCP pools.
That's what I've done on Router0:
ip dhcp pool 100
network 10.10.192.0 255.255.240.0
default-router 10.10.207.254
ip dhcp pool 200
network 10.10.208.0 255.255.240.0
default-router 10.10.223.254
ip dhcp pool 300
network 10.10.224.0 255.255.240.0
default-router 10.10.239.253
ip dhcp pool 400
network 10.10.240.0 255.255.240.0
default-router 10.10.255.253
interface FastEthernet0/0.100
encapsulation dot1Q 100
ip address 10.10.207.254 255.255.240.0
!
interface FastEthernet0/0.200
encapsulation dot1Q 200
ip address 10.10.223.254 255.255.240.0
!
interface FastEthernet0/0.300
encapsulation dot1Q 300
ip address 10.10.239.254 255.255.240.0
!
interface FastEthernet0/0.400
encapsulation dot1Q 400
ip address 10.10.255.254 255.255.240.0
I also switched Switch0 and Switch1 ports which are connected to routers to trunk mode. But I don't understand, how I should configure DHCP relay agent on Router1 and which addresses I should give to the subinterfaces on Router1. I know you can use ip helper-address on Fa0/1 subinterfaces of Router1, but I'm kinda confused about the IP addresses of all subinterfaces.
I really hope someone will help me with this problem!
