Now when RouterB receives a packet destined to 192.168.5.0/24, it will forward it out to RouterC. When RouterC receives that packet, it will see that 192.168.5.0/24 is towards RouterB and will send it back. This loop will continue till the IP TTL value in the packet header reaches zero and one of the routers drops it.
To prevent against such routing loops, distance vector protocols have some checks in place. These checks are discussed in the following sections.
