Re: [AusNOG] Optus issue in Broome, Sydney, Perth?

Not sure what media you've been watching but TC Joyce passed West of Broome and crossed the coast at Bidyadanga, about 200k's south of us around 2am today. We got a good light show the past few days but no power failures in my area so the UPS didn't need to kick in. She is a weak Cat 1 with

Re: [AusNOG] NBN NWAS and Cisco PPPoE

Hi Liam, I believe this is the result of a software upgrade on NBN NWAS towers last week and this is a known issue, NBN are working with Cisco and the wireless vendors but this was something that has occurred and is wide spread for all Cisco NWAS users. Kindest Regards, Nathan Brookfield

Ask them for a bilateral session then do something evil like put 7545 in the path :) On Thu, Jan 11, 2018 at 4:03 PM, John Alexander wrote: > That's what I've done for the time being, it would be just good to > actually use HE but anyway... > > On 01/12/2018 11:01 AM,

Bilateral peering with TPG over the NSW-IX fabric should fix that. - mark > On Jan 12, 2018, at 7:46 AM, John Alexander wrote: > > With this, does anyone know of a way of keeping HE routes, but excluding a > specific one, namely TPG 7545 which is a direct customer of

Re: [AusNOG] Megaport IX Sydney - Sudden grows in number of prefixes

I was referring to the BGP route selection rules. But as someone else pointed out, there are things like local pref that they can use, which falls within those rules… From: AusNOG [mailto:ausnog-boun...@lists.ausnog.net] On Behalf Of McDonald Richards Sent: Friday, 12 January 2018 9:14 AM To:

Re: [AusNOG] Megaport IX Sydney - Sudden grows in number of prefixes

I tried this, with 3:6939 which added 3 prepends to he (which I could see at HE's LG) but TPG still preferred to send traffic via he rather than transit, even though the path was longer... ughhh On 01/12/2018 08:52 AM, Philip Loenneker wrote: Note that you can also use BGP communities to

Whoops, indeed that is the case. It was one of the first results on Google that I found, didn't look close enough. Haven't had my coffee yet. :) On Fri, Jan 12, 2018 at 8:53 AM, Jacob Taylor wrote: > Won't that only work for traffic going from John's AS to TPG? > >

Re: [AusNOG] Megaport IX Sydney - Sudden grows in number of prefixes

Won't that only work for traffic going from John's AS to TPG? His example was from TPG to their AS - If they were to implement a prefix list filtering on ASN, then they would preference another domestic route (presumably transit) but TPG would still preference HE, which would make for some lovely

Re: [AusNOG] Megaport IX Sydney - Sudden grows in number of prefixes

Note that you can also use BGP communities to adjust how the IX advertises your subnets to individual peers using the documentation here: https://www.ix.asn.au/peering-technical/ Unfortunately you can't set a community of 0:7545 to avoid advertising your routes to TPG, as they aren't the direct

Re: [AusNOG] Megaport IX Sydney - Sudden grows in number of prefixes

Filter based on the AS Path? If the path is: You <- 58941 <- 6427 <- 7545 You <- MegaIXSyd <- HE <- TPG In the Cisco world, I would use ip as-path access-list 10 deny ^58941_6427_7545$ (The ASN's here may not be exactly what is in use, you will need to check your received prefixes) On

Re: [AusNOG] Megaport IX Sydney - Sudden grows in number of prefixes

With this, does anyone know of a way of keeping HE routes, but excluding a specific one, namely TPG 7545 which is a direct customer of HE. Traffic from them goes from Syd -> LA -> Syd -> he peering -> me.  I'd prefer to just make them stay at home so to speak instead of going around the world.
