Routers R$1,$ R$2,$ R$3$ and R$4$ are running RIPv$2$ with Split Horizon enabled. R$1$ has serial links to R$2,$ R$3$ and R$4$ as shown. R$2,$ R$3$ and R$4$ have links to other routers that are not shown. Router R$1$ has just powered up and its routing table is empty. R$1$ has just received the following RIPv$2$ packets from R$2,$ R$3$ and R$4.$ Note that these are all Cisco routers, so each of these routers incremented the hop counts before they sent these RIPv$2$ packets to R$1.$
