Having completed the Networking Essentials Course from Cisco Networking Academy, I've been practicing on Packet Tracer until I came across this scenario.
Supposing we have two intranets, A and B. Intranet A has three routers (router 1,router 2 and router 3). Intranet B has three routers also (router 4, router 5 and router 6). Intranet A's router 3 connects to intranet B's router 4.
The problem however is that they are using different routing protocols. Intranet A is using RIP while intranet B is using EIGRP. Gateway of last resort has not been set on any of the routers.
What can be done to enable hosts on intranet A communicate with intranet B (through the link between router 3 and router 4)?
