MTU Problem on Cisco 7606
by Shahab Vahabzadeh 11 Mar '14

11 Mar '14

Hi everybody, I have change my core router from 7206 VXR to 7606 with RSP720 since last 1 month. I had GRE Tunnel in 7206 with one of my regions with this config: interface Tunnel1 > ip mtu 1500 > ip policy route-map clear-df I have copy this config to new 7606 with the same config but now I have Problem with page load. For example yahoo.com totally does not work. I change Tunnel interface config to: interface Tunnel1 > ip tcp adjust-mss 1360 > tunnel mode ipip But again does not make difference, for example yahoo.com solve but put another site in trouble. I must notice that my region side router is 7206 VXR and we have not change that router, It is the same as before was. The question is what is different between 7600 and 7200 in MTU? I change "*system jumbomtu*" to *1526* on 7606 but it does not make any difference. Would you please help me in this field?

Packet Switch Node? Not sure what would be in this context. Not on the same router? How about two routers away with both THEM on the same router (a third one)? Not on a host that does anything else? Both of those actually make some sense to me, the first from a single point of failure consideration, the second regarding unrelated failures (I have to re-boot my windows PC at least once a day, most days because Firefox, the way I use it, gets itself tangled about that often and a reboot is the quickest way to clear it). -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes.

anyone ever get an HWIC-CABLE-D-2 card to work?
by Matthew Petach 09 Mar '14

09 Mar '14

I'm grasping at straws here, and reaching out to a wider community to find out if there's anyone out there that's been able to get an HWIC-CABLE-D-2 card to work. I figured it was worth giving one more shot before I call and cancel my Comcast account, as it seems silly to pay for a service I can't use. The card synchronizes with the CMTS system, does all the happy dancing back and forth with ranging, etc. and then just hangs waiting for the TFTP transfer to complete. Tried different cables, removing all splitters, plugging in right at the entry point to the facility...no change. :( Here's the config on the interface: netflight-1841#show run int cable-Modem 0/1/0 Building configuration...

Who uses ARIN's IRR?
by Jason Lixfeld 08 Mar '14

08 Mar '14

I don't need to use it much, but when I do, it's an ever-increasing royal pain in the ass. My current plight revolves around not being able to get full dumps of objects. Certain mandatory fields in objects are 'filtered' and/or replaced with dummy data. This poses a problem because one can no longer simply cut and paste the output, change the necessary bits and fire it off to rr(a)arin.net for processing. WhoisRWS doesn't seem to have hooks into the IRR database like RIPE seems to have gotten right. So how do people tend to get around this? Is there something that I'm missing or do people just throw their hands up and move their IRR data to RADB or something?

Need ARIN routing registry help
by Meshier, Brent 07 Mar '14

07 Mar '14

Level3 won't let us advertise our netblock because RADB shows it owned by Telkom South Africa, but it's clearly assigned to us by ARIN. I've raised a question with ARIN, could really use someone there that could expedite. On that note, when ARIN re-assigns networks, shouldn't they clear out related entries in the routing registry? --- Please refer to http://www.amherst.com/amherst-email-disclaimer/ for important disclosures regarding this electronic communication.

valley free routing?
by William Herrin 07 Mar '14

07 Mar '14

Hi folks, Can anyone tell me about a situation in which a route which was not valley free was not a result of a misconfiguration or a bad actor? For those who don't recall the terminology, a network path is valley free if it crosses exactly zero or one free peering links when traveling between the two endpoints. Thanks, Bill Herrin -- William D. Herrin ................ herrin(a)dirtside.com bill(a)herrin.us 3005 Crane Dr. ...................... Web: <http://bill.herrin.us/> Falls Church, VA 22042-3004
