stupid question but does this mean

7 weeks and 0 days?
I mean looks like it but I have no idea what it would be used for? thanks

Age of the route. So that router has known about that for the specified amount of time.

itdaddy

is that the last time it used that route? I am confused when does it appear or when does it change? does it go away and come back?

It's when the route was learned. So that route hasn't flapped in X amount of time. It's the route's age.

itdaddy

so it is saying the last time it was used was x amount of time?

flapped being a term = used ?

No, it's stating the period of time since that router learned about the route from it's neighbor. If the link to the neighbor had gone down and back up (flapped) then the route age counter would start again as the route would have been re-learned. Either from the same neighbor or another source.

itdaddy

so it is time based off of a route being learned and relearned only not the use of a route since I found this in the routing table it is only the time from when the route was learned only not necessarily used..right?

Straight from Cisco:

"Specifies the last time the route was updated (in hours:minutes:seconds)."

In your case, it is in the weeks.

Has nothing to do with router usage. It is simply the time that has elapsed since that route was entered into the routing table by whatever routing process put it there.

itdaddy

thanks Heero

You lost me.

LOL.

it's when the route was placed in the routing table.

If you have CEF turned on, though, the FIB should be getting referenced, instead of the RIB, for subsequent lookups.

And I'll leave it up to you to look these up, as it might hurt you to explain too much.

thanks guys I have it..yep don't hurt me too much..thanks
