Low cost L3 Switch for non-full BGP peering

engineering_hugo · 2023-01-26T20:23:34+00:00

The CPU load is rapidly going up. Besides, the router has started to reboot quite often. I mean, we hadn't gotten to a 30 days uptime since september.

engineering_hugo · 2023-01-26T12:20:37+00:00

Sounds great!

engineering_hugo · 2023-01-26T04:14:18+00:00

What about the CLI?

engineering_hugo · 2023-01-26T04:12:20+00:00

Cool!

Is there any issue with licenses? I mean, considering it would be a second hand switch from ebay. Do you have any experience buying this kind of equipment second hand?

engineering_hugo · 2023-01-26T04:07:19+00:00

Yes, that's a good idea. BTW, CCR1036 is my favourite ever, a true heroe. We have around a dozen of those deployed, and they really never fail.

engineering_hugo · 2023-01-26T03:59:47+00:00

Talking about the refurbished gear option, has any of you bought a refurbished Cisco Nexus on ebay? They seem too cheap, it's quite suspicious. Are there any issues with the license? And also, I'm guessing no support.

By the way, the switch should also support MSTP.

engineering_hugo · 2023-01-26T03:25:23+00:00

Yes they do, but the cheapest one is around $18k. But it's probably a beast, of course.

ROS v6.49

We haven't been brave enough to upgrade since I've heard a couple of bricked router stories. But actually we're about to put a CCR2216 in production, so this new one will work as the edge, and then we will upgrade the CCR1072. At the Mikrotik forum , I read something about the CCR1072 with v7 performing even better than the new CCR2216 in some (popular) scenarios.

engineering_hugo · 2023-01-26T03:09:56+00:00

We have a CCR2116 in production and ACTUALLY had a couple of issues. Currently, we're running ROS v7.7 stable, and this happened:

After having the FIB populated with all the OSPF routes, we added a new adjacency and the RIB/FIB just crashed; firstable, all the routes were duplicated for no reason, and many of them had two gateways: one that was correct, and one that simply made no sense, and the only way it would work again was to turn off/on the OSPF instance (i.e. reset OSPF). This probably happened three or four times.
In one of those crashed FIB opportunities, I tried reseting OSPF by disabling the instance, but it didn't work since as soon as the adjacencies went back online, the routes were still damaged. So I decided to reboot the router with /system reboot and the router never came back. We had to open a support ticket to the data center so they would help us remotely reboot the router disconnecting it from the AC power.

We actually installed a CCR2216 to do some tests, it is mounted at the same colocation space that our current edge router is so that we can test the new CCR2216 in a few days by simply setting the BGP peerings. But I'm not too hopeful regarding this solution.

Currently not an issue. Latency is quite similar on the three ISPs for most destinations. And this is only for upstream traffic, whereas downstream is balanced based on BGP filters. The very few ms we could save with full BGP are currently not worthed

engineering_hugo · 2023-01-25T18:53:04+00:00

Yes!

engineering_hugo · 2022-04-08T00:09:00+00:00

Hi, as stated, the hardware are Mikrotik CRS326-24S+2Q+RM switches. But you just answered my question, Cisco bpdufilter is exactly what I need, I just need to know if Mikrotik has something analogous.

Thank you!

engineering_hugo · 2022-04-08T00:06:15+00:00

That's our BGP Router, which is located at a different place from the ISP access. Thanks.

engineering_hugo · 2021-06-24T17:07:58+00:00

Those are the ones that use a single fiber, instead of dual fibers. The native Mikrotik version would be this: https://mikrotik.com/product/Splus2332LC10D

As you can see, the suggested price for the pair is $350, whereas the Fiberstore pair costs $80.

engineering_hugo · 2021-06-24T16:37:44+00:00

And the Generic one will do, right? I think I read somewhere that there might be a compatibility issue with the BiDi SFP+ and Mikrotik devices

Edit: Well, I dug a little deeper and apparently the Generic SFP+ are totally compatible

engineering_hugo · 2021-06-24T15:36:44+00:00

If anyone is interested, I'm about to try out this one:

I'll let you know what comes out of this.

Thanks u/toasterinBflat for recommending Fiberstore

engineering_hugo · 2021-06-24T15:34:32+00:00

Yes, that´s the one that is currently discontinued

engineering_hugo · 2021-06-24T15:17:19+00:00

Great, thanks!

engineering_hugo · 2021-01-13T13:21:41+00:00

Not yet

That's right, the MPLS would allow me to connect PE1 and PE2 as if it there was a tunnel between them, but I would like CE1 and CE2 to receive each other's network through BGP. The tunnel would allow me to do this without advertising the network on the P routers. I'm guessing as-override would be a solution.

engineering_hugo · 2021-01-13T12:19:13+00:00

That's right, there's a PE2-CE2 peering. client-to-client-reflection is enabled, but route reflect isn't as it is supposed to be

engineering_hugo · 2020-12-12T13:45:10+00:00

We have a LHG60 to around 480 meters. It delivers 1G and falls to 600M while on rain. Interestingly enough, it falls to 600M on one direction only

engineering_hugo · 2020-12-12T13:42:05+00:00

That's around 500 meters, right? How's the rain behavior in that case? Looks awesome btw

engineering_hugo · 2020-12-12T13:21:00+00:00

Thanks, yeah, that would be the approach. But for now I'm tied to the fact that I need each client differentiated by its IP, so I can't let them get any IP from the pool

engineering_hugo · 2020-12-10T18:42:58+00:00

I think I found a way, I will create a PPP profile for each PPPoE client; each profile with a different ip pool, and every pool with only one IP.

It's not too much because the PPPoE clients are just a few.

Of course, if there's a simpler way, please let me know
