Final piece of the puzzle

Hi guys,

It's been a great vacation, tons of interviews and lots of lab times so I'm quite happy. Now I have one final act. Getting the 1721 router to route between the networks.

I'm curious if I need to do inside nat and outside nat on the 1721 now to get this to work or will simple routing work.

I can connect from both 2600 routers to the 1721 router and the ip address of the 1st IP in the next hops'd network that sits of the 1721 but I can't ping past that. I'm sure it's a routing issue and I haven't caught it yet or it could be something new to me; not sure.

Would really like to put this lab to rest and close on a good note; if any of you see the issue let me know.

Possible need a static route on device connected to 1721?

What's connected to it?

Deathmage

the 1721 has two wic 1t's on it and the integrated Ethernet is connection to the backbone (192.225.225.0/27)

I'll see if the static helps. not really sure what else is broken on it....both side of the network up to the 1721 are working and both feed into the 1721 from both 2600's perfectly fine it's just pinging one 2600 thru the 1721 to the other 2600 that's the problem.

xnx

I think I mis-understood your problem then... so basically the backbone connection works - but you can't ping from 2600 to 2600?

Do a traceroute from R3 to R4 and paste the output here

Exactly, I can't bridge the 2600's to each other; the 1721 is the bridge and also the connection to the core backbone (home LAN) which work from the 1721, it can connect to the primary LAN fine.

here this is what I can and can't do. Look at the picture, maybe the flowchart will help.

erg typo in flowchart, its 130.6 from 1721-R2

let me get the trace routes.

here is the traceroutes:

Here is the 1721 (in the middle) :

Looks like packets from R3 to R4 are being dropped at R2 as R2 has no route to the 172.16.8.0 subnet

I'll double check the routes in the morning and see if that can be corrected. Sometimes you need a 2nd set of eyes. - I'll let you know!

added these routes to the 1721, the 1721 is on the same power strip as my Procurve so it's still on, so just edited it.

@ xnx - thanks so much; I think this will resolve the matter. I was always thinknig of the lower vlans on the access switches but I totally overlooked the 172.16.8.0 and 172.16.7.0 subnet's and it makes sense now....

I guess my brain was just shot yesteterday and didn't see it till now...

xnx

No problem, traceroute is your friend - as long as you take it step by step
