A specific static route to a remote loopback is the simplest possible deterministic routing test. The loopback as the ping source proves end-to-end reachability with a stable address. This lab walks through configuring static routes across R1, R2, R3 of the base topology to make 10.255.0.1 reach 10.255.0.3 end-to-end.
What you will learn
- How to configure a static route to a remote /32 (loopback)
- Why every router in the path needs both forward AND reverse routes
- How to use a loopback as the source IP for ping and traceroute
- The role of the
traceroute sourceargument
What this lab does NOT cover
- Routing protocols that learn these routes dynamically (OSPF, EIGRP) - covered in ipc-04 through ipc-11
- Default routes - that is ipc-01
