Hello,
I need your suggestions on whether following DHCP design works as expected or it creates any technical issues. I know the design is not the best design and it has some flaws.
-It contains 2 DHCP servers.
-Each server is capable of serving all the clients in the network.
-To maintain redundancy, instead of using Split scope or MSCS, we are setting up 2 DHCP servers with 2 different IP scopes.
-On DHCP1 server, 2 DHCP scopes are created as mentioned below but it serves only 1 DHCP range. All IPs in the 2nd range are added to exclusions so that other DHCP server can serve that range.
172.16.20.0/24 -- Provides these IPs to clients
172.16.30.0/24 -- All IPs on this range are added to exclusions so that other server can serve this range
-On DHCP2 server, same DHCP scopes are created as DHCP#1 but it serves second IP range
172.16.20.0/24 -- All IPs on this range are added to exclusions so that other server can serve this range
172.16.30.0/24 -- Provides these IPs to clients
-8 days lease period
If the design is like this,
-Will there be any technical issues with this design? I know the split scope is better option but if the design is like mentioned above, will it create any issues?
-When clients try to renew the IP when both the DHCP servers are online, does this design create any issues?
-If one of the DHCP servers goes offline for long time, does the clients have any impact like going out of network briefly, etc?
Thanks.
