Replace four routes with one
A router carries four separate static routes to four contiguous /24s. Collapse them into the single summary route that covers exactly those networks.
Scenario
r1 reaches four networks behind r2 and currently carries a separate static route for each:
10.1.0.0/24, 10.1.1.0/24, 10.1.2.0/24, 10.1.3.0/24. They're contiguous, so one summary route
can replace all four.
Your job
In r1/frr.conf, replace the four /24 static routes with the single summary route that covers
exactly those four networks (and no more), via the same next hop 10.0.12.2.
What "done" looks like
A single static route that covers exactly those four /24s and nothing more, via the same next
hop, with the four /24 routes removed.
Teaches: route summarization (supernetting). Four contiguous /24s aggregate into one shorter prefix, which shrinks the routing table without advertising address space you don't actually have.
What gets checked
Your solution is verified against each of these:
- A single summary route replaces the four separate /24s
- The summary covers all four /24 networks
- The four individual /24 routes are gone, replaced by the summary
