1. Network Topology Overview:
Three branches, each with:
- A router (CAIRO, GIZA, MAADI)
- A switch
- Connected end-user devices (PCs or laptops)
- DHCP automatically assigns IPs

3. DHCP Configuration Summary
Each router runs a DHCP pool to automatically assign IPs to local devices.
DHCP excludes the router’s IP as a default gateway and assigns remaining
usable ones.
4. Summary
- Every branch uses a /29 subnet (supports up to 6 hosts, can be edited later).
- Routers serve as DHCP servers and default gateways.
- Devices receive IPs dynamically in their subnet.
- IP ranges are non-overlapping and properly segmented.
