"When using RIP, the maximum number of hops, that data can be forwarded through, is fifteen. If the destination network is more than fifteen routers away, it is considered unreachable"
what about the internet we're using
does it more than 15 routers around the world connected ?
anyone can explain
thx | |

plz explain | |

| Braveheart - I'll try & help you out - not that I know that much but....
Rip is a distance vector routing protocol and is limited by hop count as a metric (although I think you can extend it - I know you can extend to time to live of a packet)because of the limit on hops & various other reasons RIP is not used to route internet traffic.I think RIP is an IGP: Interior Gateway Protocol for inside AS's (networks under one administrative control)- also there is a newer form called EIGRP.
Instead - for routing between these AS's EGP: Exterior Gateway Protocol is used - an example of this is BGP: Border Gateway Protocol.
So RIP is not used for routing the Internet & is only really suitable for small(ish) interior networks.
If you want more info have a look at Cisco's ICND course.

Do you mind if I ask how you do this?!
And what exactly is "routing the Internet" supposed to mean?!
Cheers! | |

| Hello DMFTEI?

Thankyou for your response to my reply - It actually made me go back & look at the books - I thought that you could extend the ttl of a packet but maybe I was confusing it with holddown timers or something - anyway thanx for pointing it out.
As for putting 'routing the Internet' - maybe I should have put 'routing across the Internet' or routing between Autonomous Systems. If you have any better suggestions for Grammar - then let me know kid.
It's good that a moderator with so much experience can bully junior members of the forum & create an environment where everyone can learn without prejudice or people sneering and looking down their noses.
I do not mind being corrected - don't get me wrong - I have a lot to learn - but do not forget - no-one comes out of the womb knowing the ins & outs of Cisco indigenously. Oh - except DMF....whatever | |

Hello monkeyboy! My username is dmaftei, not DMFTEI... 
Thankyou for your response to my reply
You're welcome!

Always a good idea, huh?

Yeah, maybe you should have...
If you have any better suggestions for Grammar
I didn't say anything about "Grammar"!!
then let me know kid.
I would suggest you keep your tone polite. I didn't call you "kiddo" or stuff like that!!

I don't get it! What moderator?! Who's bullying junior members?! Who's "looking down their noses"?!
I do not mind being corrected - don't get me wrong - I have a lot to learn - but do not forget - no-one comes out of the womb knowing the ins & outs of Cisco indigenously.
Apparently you do a lot! You made a statement, and I asked you to explain it. That's all!
Oh - except DMF....whatever
Are you referring to me?! You know, my username is dmaftei, not DMF...
Cheers, and relax!! | |

| Hey everyone.
You can in fact change the TTL of an IP packet. If you're simply pinging, use the - i option. Otherwise, look to the registry (assuming you're running a Winodows box) for TTL...don't ask me the path, because I don't know off the top of my big head.
HTH. | |
|
| Relaxed & V chilled - what I said stands - apologies for giving you moderator status.
Obviously I hit a raw nerve there. There is absolutely no need to look down on Junior members of the forum & from reading the forum I have seen you do the same thing bfore.
The object of this forum is to assist other users & increase one's own learning - not to put people down.
Poor show m'lad
MS
Anyway - nuff said | |
|
| If you feel that I "look down on Junior members" or "put people down"... that's your problem, not mine...
Let's make a deal: I'll put you on my "Ignore list", and you put me on your "Ignore list". What do you think, m'lad? | |
|
| errr....did someone say something????? | |

Hey firechicken,
I guess you're right. I suppose it can be done on unix machines too. Since the answer was so simple, makes me wonder why some poeple were offended that I asked...
Cheers! | |

| Ouch...play nice in our sandbox!

| I would close the thread. Too tempting to "look down"...  |
