Routers do not automatically know where to send packets for non-adjacent networks. For each router, inspect its routing table: Ensure it has a route for every network in the simulation.
Convert a mask like /27 to its decimal format ( 255.255.255.224 ) on a whiteboard.

Look at the interface connections. Interfaces plugged into the same switch or direct wire share a local network. They have IP addresses that belong to the exact same subnet range. Step 2: Validate the Interfaces Check every defined IP address against its subnet mask.
| Concept | Explanation | |---------|-------------| | | 32-bit address (e.g., 192.168.1.1 ) | | Subnet Mask | Defines network vs host portion (e.g., 255.255.255.0 = /24 ) | | Network ID | First address of a subnet (host bits = 0) | | Broadcast | Last address of a subnet (host bits = 1) | | Gateway | Router interface that forwards traffic to other networks | | CIDR | /24 = 256 IPs, /30 = 4 IPs | Routers do not automatically know where to send
. This flips the first two bits to 1, leaving the rest as 0: 11000000 . 2. Subnet Masks and CIDR Notation
