I'm reading Routers and Routing Basics (CCNA 2 Companion Guide) and have a question about RIP route poisoning. If you have two connected routers (R1 and R2) and one of R2's interfaces fails, it will advertise this network to R1 with a metric of 16.
The book says that after this route with metric 16 gets installed in R1's route table, R1 will forward packets to this network to R2. Is this correct? I thought that with an infinite metric, R1 would drop the packet. No?
