Re: IPv6 over vxlan+evpn Arista?

Do you need to carry the v6 af in the underlay? I’ve used 6pe/6vPE to carry v6 over v4 next-hops in the overlay without issue, but can’t say I’ve tested a dual-stack vtep. On Fri, Jul 10, 2020 at 08:07 David Hubbard wrote: > Hi all, was curious if anyone is doing dual stack v4/v6 over Arista’s >

Re: 100G-LR1 (DR/FR)

Tangentially related to xR1, have any of you started deploying SN connectors on your 400G head-ends? It looks like a pretty clever technology, adding discrete connectors per lane, but curious what the adoption has been thus far. On Tue, Apr 4, 2023 at 8:55 AM Mikael Abrahamsson via NANOG wrote:

Thanks for the transparency, Vincent. Are you able to share how the AS-Path became mangled to begin with? I’m assuming this was some kind of route optimizer, but maybe something else going on? On Mon, Oct 23, 2023 at 07:32 wrote: > Hello everyone, > I'm working for MilkyWan / AS2027 and I wanted

So not only are they hijacking prefixes, they're leaking the /30s to their peers. Failure through and through. On Saturday, April 1, 2017, George William Herbert wrote: > > Hey, Bharti, knock that off. > > http://bgpstream.com/event/78126 > http://bgpstream.com/event/78125 > http://bgpstream.co

Re: Anyone using Arista 7280R as edge router?

I've deployed a 7280SR in that role. Needs the FLX model/license, and a special TCAM optimization command to install all the routes in hardware. Right now, just pulling a single v4 feed, expanding to a second soon; no v6 yet. Overall, no major issues with it, but Arista seems to be pretty close-lip

Re: 10G MetroE 1-2U Switch

I'd avoid the 7280R for this. Works great as a P router for cheap, fast label switching, but their VRF implementation is lacking with both route-leaking and MP-BGP address family (other than standard ipv4+ipv6) support being nonexistent. On Thu, Apr 13, 2017 at 3:12 PM, David Hubbard < dhubb...@di

Re: Need recommendation on an affordable internet edge router

I use the 7280R in production. Love it. Pros: Cheap, fantastic API, can take (current) full tables of v4 and v6. 6x100G w 48x1/10G gives lots of flexibility. Cons: Lack of proper VRF support and minimal bgp address families. (If you want strict isolation, or can use a separate device for route le

We're using a mix as well, some QSFP28 AOC, others DAC. One thing that you need to keep in mind about the DACs is going to be the bend radius. These things are girthy af, so make sure to either overestimate your runs slightly, or buy one to test first. On Thu, Sep 14, 2017 at 11:54 AM, Hugo Slabbe

For Enterprise/DC, it works great. For service provider, they're not 100% yet.

They'll work great as a P-Router, but if you ne
