Re: Direct peering to Yahoo! unstable over the last few days

Thanks, Jeremy. I had always assumed Yahoo!'s gear was colo'd at MICE.

I also happen to know that Yahoo is connected via a longhaul circuit into MICE. I have a wavelength with the same provider that would logically take the same path based on the same endpoint locations, and they have been having intermittent DC power issues in one of their huts for over a week now. They currently have an electrician on site to try to determine the intermittent piece of equipment. -----Original Message----- From: MICE Discuss [mailto:MICE-DISCUSS@LISTS.IPHOUSE.NET] On Behalf Of Frank Bulk Sent: Saturday, August 18, 2018 11:12 AM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: [MICE-DISCUSS] Direct peering to Yahoo! unstable over the last few days Anyone else seeing the same as us?

Re: Direct peering to Yahoo! unstable over the last few days

by Jeremy Lumby

I can confirm the same on my router. I also happen to know that Yahoo is connected via a longhaul circuit into MICE. I have a wavelength with the same provider that would logically take the same path based on the same endpoint locations, and they have been having intermittent DC power issues in one of their huts for over a week now. They currently have an electrician on site to try to determine the intermittent piece of equipment. -----Original Message----- From: MICE Discuss [mailto:MICE-DISCUSS@LISTS.IPHOUSE.NET] On Behalf Of Frank Bulk Sent: Saturday, August 18, 2018 11:12 AM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: [MICE-DISCUSS] Direct peering to Yahoo! unstable over the last few days Anyone else seeing the same as us?

Re: Routing of non-IX traffic

by AnthonyAnderberg＠nuvera.net

Interesting - today I've learned that although IOS XR has Proxy ARP disabled by default, IOS XE has it enabled by default: nuveragw1#show ip int te0/3/0 | i ARP Proxy ARP is enabled RP/0/RSP0/CPU0:bbvgw1#show ip int te0/0/0/2 | i ARP Proxy ARP is disabled I’d agree that it’s not expected behavior in this context, so will disable it on Nuvera’s XE router.

Like Doug, I only have 45.60.73.0/24<http://45.60.73.0/24> from transit connections. So a traceroute from my MICE interface should ARP and die (I would think).... When I traceroute to 45.60.73.16-- my router sends out an ARP request, as expected.

At one level I agree with you, especially when you are talking about IXPs. However, facing userland, proxy arp plasters over a myriad of silly misconfigurations and typos. Which from a TAC and help desk point of view is a good thing, many tickets that are never opened, because it just works.
