Engineering Joins

Lesson 29 of 35 in Coddy's LAN Labs course.

Engineering gets its own subnet, 10.10.2.0/24, behind the router's eth1. Same recipe as Sales: address the router interface with the .1, then the desktops.

Now the interesting part. The router sits in both subnets, so the path between Sales and Engineering exists. But no desktop knows about it yet: without a default gateway, eng1 cannot even try to reach Sales. The next lesson fixes that; this one just proves the gap is real.

Challenge

Easy

Add host eng1, cable it to switch eng, address it 10.10.2.11/24, give the router's eth1 the address 10.10.2.1/24, then ping sales1 from eng1.

Expected output:

Added host eng1
Linked eng1 (eth0) <-> eng (port2)
eng1 eth0: 10.10.2.11/24 (mask 255.255.255.0, network 10.10.2.0/24)
core eth1: 10.10.2.1/24 (mask 255.255.255.0, network 10.10.2.0/24)
eng1 -> sales1: unreachable (different subnet, eng1 has no gateway)
