I don't know what Google and Moratel's peering agreement, but "leak"? educate me, Google is announcing /24 for all of their 4 NS prefix and 8.8.8.0/24 for their public DNS server, how did Moratel leak those routes to Internet?

I thought a customer originated the prefix. Original question still stands. Which attribute do you expect Google to set to stop this? Hint: Don't say No-Advertise, unless you want peers to only talk to the adjacent AS, not their customers or their customers' customers, etc. Looking forward to your answer. -- TTFN, patrickOn Tue, Nov 6, 2012 at 9:02 PM, Patrick W.

Google is peering with Moratel, if Google doesnotwant Moratel to advertise its routes to Moratel's peers/upstreams, then Google should've set the correct BGP attributes in the first place.That doesn't make the slightest bit of sense. If a Moratel customer announced a Google-owned prefix to Moratel, and Moratel did not have the proper filters in place, there is nothingcould do to stop the hijack from happening. Exactly what attribute do you think would stop this? -- TTFN, patrickOn Tue, Nov 6, 2012 at 3:35 AM, Anurag Bhatia <me () anuragbhatia com>wrote:Another case of route hijack -http://blog.cloudflare.com/why-google-went-offline-today-and-a-bit-aboutI am curious if big networks have any pre-defined filters for bigcontentproviders like Google to avoid these? I am sure internet communitywould beworking in direction to somehow prevent these issues. Curious to know developments so far.
