DHCP Super scope

Combination of 2 scopes. Ex: 192.168.1.1 and 192.168.2.1

We combine these 2 to lease out the ipaddress no matter the network ID

One client can get 192.168.1.1 and another client can get 192.168.2.1

So now when client A wants to talk to client B. they can’t communicate as the network ID’s differ. Now we need to install RRAS on DHCP server.

In a scenario like this we need to have the default gateway as ipaddress of DHCP server.

Fault tolerance in DHCP

Coming to fault tolerance, we can’t have 2 dhcp servers with same scopes. We can only have 2 scopes with ipaddress divided.

If DHCP server 1 as 192.168.1.130 , we can have DHCP server 2 with scope as 192.168.131.254.
