NEED Some HELP
Hi Nanog Members, I've been troubleshooting this problem for a few days already but i'm still unable to fix it. I think it's now time to ask some help from Nanog members. I cannot ping the IP on my Cisco 6509 from the internet. Here are the setup: *Internet*---(copper)--*GSR*(fiber)---* Cisco 6509* This setup is NOT OK - I cannot ping *Internet*---(copper)--*GSR*(copper)--- *Cisco 6509*This setup is OK - I can ping(this is directly connected to the PRP2) NOTES: - I am using PRP2 on my GSR and the fiber is connected to the 4xGE module - I have a default route from Cisco 6509 to GSR - From the 6509 I can only ping the IP addresses on the GSR, addresses outside the GSR are not reachable - From the internet, I can only ping up to the GSR - I can ping from GSR to 6509 and vise versa - The IP on the 6509 is configured on the interface that is directly connected to the GSR. Thanks, -bong

Quite out of the context of the connectivity issue you're trying to troubleshoot, it's in fact extremely desirable to have your 6509 (and all your routers, for that matter) unpingable from the outside your own network. The BCP is to use iACLs, CoPP, et. al. to keep out all unsolicited traffic headed to, as opposed to through (like traceroute, pinging customer hosts, etc.), your network infrastructure. --- Roland Dobbins rdobb...@arbor.net // http://www.arbornetworks.com Sorry, sometimes I mistake your existential crises for technical insights. -- xkcd #625

Re: NEED Some HELP
Hi Roland, My GSR and 6509 are newly installed and no ACLs in place. You can try to ping 180.178.73.1 and 180.178,73.2. 180.178.73.1 - GSR 180.178,73.2 - 6509 I can only reach 180.178.73.1 from outside. I cannot reach 180.178.73.2 which is the IP of my 6509. Not sure if this has something to do with the hardware. I am just wondering why I can't reach 180.178,73.2. Like I said earlier in my email, I have the default route from my 6509 to te GSR. My GE module is inserted to the GSR slot 1. Is the hw-module config requred on the GSR? Please help.

Even if i guess everybody is aware this is thankfully coming at some stage, and i personally find the shortly definition late 2009 a bit disappointing, i find the point being another: In late 2006 it was more or less monumentally announced that the paths of the switch and the router were to get separate: the 6500 and = SXH releases on one side, the 7600 and = SRA releases on the other. Then i see 32-bit ASNs being kindly implemented on the switch first, in SXI - with SRD for the router being released roughly in parallel; and one can amuse himself by reading issues people stumble upon with SXI. OK, a fuck-up on the way - it can happen: http://www.cisco.com/warp/public/707/cisco-sa-20090729-bgp.shtml And finally, yes, 32-bit ASNs for the router will come: by the end of this year and on a new release: SRE. Which, re-phrased from an operator point of view, essentially means: a candidate release for a production deployment is not less than another 1 year away. And frankly pages like the one below, with no mention of plans for the 6500/7600 platforms whatsoever, are not encouraging at all: http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6554/ps6599/data_sheet_C78-521821.html Cheers, Paolo

Re: Does Internet Speed Vary by Season?
Hi Fred. I think you are referring, in the case of hierarchical synchronous architectures (SONET/SDH), to the absolute periodicity of the timing coming from clock sources. Frame slips and overwrites can occur when too many ppm lagging or leading are exceeded, as I believe was implied in your post. In contrast, I believe the notions that are being discussed in this thread have more to do with the effects of temperature coefficients of metallic conductors during shifts in outside temperature conditions, and the ensuing changes in the nominal velocity of propagation that accompany those changes, relative to the speed of light. In any case, I have been following this discussion from its beginning with a great amount of interest, finding it a great memory jogger from times misspent in my youth. I started a parallel discussion on my forum, where today I responded to another poster with the following observations, for anyone interested.

Re: Does Internet Speed Vary by Season?
Maybe I'm way off.. Maybe its view of KISS but as engineers we should all be looking for the simplest answer. To me they key in Dragos' post was usage. All physics aside, the warm weather (seasonal) people go out more, use the internet less. In cold months, we stay in, use the net more. As for document any of us that run networks have seen this well document going back many years in our mrgt graphs. But then maybe he was refering to the physics, and I just try to simplify things to much. Have.

Not true with modem type technologies, where the available transmission rate is a function of how many available frequency space slices are deemed to be good at any one time. This isn't really like SDH (from what I've read of SDH, anyway.) Adrian

RE: Does Internet Speed Vary by Season?
Having worked in Operations at various ISPs in rain-riddled Houston for 1.5 decades, I can say that when it rains, water gets into the copper lines in the ground and caused increased copper-based local loop failures. That experience leaves me open to believe that where the internet backbone is copper based, when it rains, failures may ensue due to old or improperly installed outside plant and could cause failures which would slow down the internet. I would also conjecture that more people would be on line during bad weather, so that internet usage would increase and perhaps over-wrought links (copper or otherwise) could have some congestion. Finally, in those places where the internet is experienced through wireless links, some may see weather related slow downs.
