Good Day All,

Thank you,
Lester

Hello,
Only a few steps required:
ip dhcp pool POOLNAME
network "Subnet address" "Mask"
default-router "GW address"
and you need an interface which is configured with the GW address.

Please retae me if I helped.

Hi
My problem is that. I have a router with two interfaces fastethernet which are directly connected with one switch(2950). I have only one dhcp pool for the one interface. Today i put another dhcp pool for the other interface. I do not have Vlans at my switch. What address do clients of the switch will get. Can i configure that.
Thanks

Hello,
If you have two interfaces on the router with two pools following the situation:
router:Fa0/0 and Fa0/1
Fa0/0 connects to switch over an access link ( switch is configured as access port, not trunk)
If the pool for Fa0/0 is
10.0.0.0/8 and tha IP of the Fa0/0 is in the is range than a host on the switch will get address from this pool and not from Fa0/1.
DHCP pool fits to the interface. Fa0/1 pool is only for hosts(switch) connected to this port.

Hello to you also
Both interfaces of the router are access-links not trunk-links. Both have dhcp pool. Both are connected with the same Swithc. I plug in a client with dynamic address. Which ip address will this client will get. From which pool i mean
Thanks

Hello Moses,
You do InterVlan routing with your router, Fa0/1 and Fa0/0 is on your router, two different subnets with two different pools. From the router you have two uplinks - access links. These links are terminated on two different Layer 2 vlan on the switch. If Fa0/0 is terminated on vlan 100, hosts in vlan 100 will get IP address from Fa0/0's dhcp pool, if Fa0/1 is terminated on vlan 200 on the switch all hosts will get ip from Fa0/1's address space.
Fa0/0 dhcp pool: address of the interface is in the pool
Fa0/1 dhcp pool: address of the interface is in the pool, interface address is member of the subnet (that's will be the GW)

Hi again
As i understand you mean there is no reason to have this design and connection if i do not want to create any Vlans on the Swithc. Otherwise what's the reason to connect two routers interfaces in one Swithc right.
Thanks

Hi,
DHCP clients broadcast the DHCP request. A DHCP client may receive offers from multiple DHCP Servers and can accept any one of the offers; however, the client usually accepts the first offer it receives.
DHCP Server matches the DHCPDISCOVER with DHCP pool(s) that contain the subnet(s) configured on the receiving interface. If the interface has secondary IP addresses, the subnets associated with the secondary IP addresses are examined for possible allocation only after the subnet associated with the primary IP address (on the interface) is exhausted.
Why are you using 2 pools in the first place ?

The reason is why i want to use two pools the problem which i found it like that from the guy when he left is why have two interfaces of router connected to the same Switch. I can not understand the reason.
Thanks

Hi,
He might have been doing it as redundancy, but it is a poor redundancy design as it is only 1 router and 1 switch, if you can't find any other logical reasons, then i encourage you to only use 1 interface.
The other reason to have 2 interfaces, is if you need to have 2 subnets, and then i encourage you to use also VLANs on the layer 2 switch, and thus you'd have full isolation and also you'd have separated the use of the 2 DHCP pools, 1 pool per each VLAN/subnet.
I hope that i've been informative, please don't hesitate if you have further questions.
HTH,
Mohammed Mahmoud.
