I am preparing itself for the CCNA exam, and currently reading the INTRO course. In the chapter 14 of the book, we can see a basic routing concepts.
In the differences between, RIP-1 and RIP-2, we have several options that among them I cannot understand two of them.
RIP-2 Includes a next-hop router IP address in its routing update: A router can advertise a route but direct any listeners to a different router on that same subnet.
Uses external route tags: RIP can pass information about routes learned from an external source and redistributed into RIP. Another router then can pass these external tags to that same routing protocol in a difference part of the network, effectively helping that other routing protocol pass information.
Please someone explain this differences to me.
Sorry about my bad English.
