# Why the Hop count for RIP is given 16 as unreachable. One reason for this Count-to-infinity. Is there any other reasons for this?

RIP permits a hop count upto15, so anything that requires 16 hops is deemed unreachable.In other words , after a loop of 15 hops, network will be considered down .

This is used mainly to avoid ROUTING LOOPS

Thats ok. Why the Hop count is 16 as unreachable. Why not 20 or 25 etc.

because the defined infinite-metric -value for RIP is 16.

It is because, by the hop count reaches 16, the packet will have travelled the globe ...

This is some sort of value determined by simulation ...so beyond that hop, if the packet keeps on travelling, it means it has fallen into some sort of loop...

if we have a finite hop count value(say 10k), it will increase the packet header size.

for normal networks, it is better to give only 2 bits for hop count rather than giving some kilobytes.

RIP official max hop count is only 15. Whatever more than 15 is unreachable.

RIP Max Hop Count is 16 which means 0 to 15. If it crosses that value then network has loop.
