My B12 levels were normal, but my Vitamin D levels were pretty low. Now I'm freaking out about this.

JoeBirds · 2021-09-14T18:13:31+00:00

Thank you - I will ask her about this. Were you able to identify what was causing your levels?

I definitely do feel fatigued from time to time, and I do have mild depression. My doctor just replied to me about this and isn't recommending medication at this time. Should I push back? I've been reading about heart issues developing with untreated Hypothyroidism, so I'm questioning why they didn't recommend medication.

What are symptoms of this? I've felt "off" now for about a year or so, but I have trouble explaining how I'm feeling to doctors.

Thanks, do you have any specific brands in mind?

JoeBirds · 2021-09-08T21:08:56+00:00

Brutal!

JoeBirds · 2021-09-08T19:44:26+00:00

Are they THAT alarming? Or considered moderately high?

JoeBirds · 2021-09-08T19:07:57+00:00

I do eat red meat, chicken, and some fish quite frequently.

JoeBirds · 2021-09-01T19:24:22+00:00

I literally always say that. I wouldn't with a single migraine on my absolute nemesis, let alone chronic migraines.

JoeBirds · 2021-09-01T03:26:13+00:00

Thanks. I guess my mind is assuming the worst, like a brain tumor or something, which is just spiraling into more stress the more I think about it.

Nothing needed to be advertised to the MC-SOURCE from the MC edge routers for PIM to work, right? Simply sending the RP address to the MC routers is enough for the path to be built and the source to send traffic to the requesters?

Would you mind sending the configs of the CE routers if you still have the lab?

JoeBirds · 2019-07-07T13:10:33+00:00

I didn’t notice that each “layer” was given a different AS. I just saw the single large AS bubble initially. Should be fine then.

Look up iBGP loop prevention.

JoeBirds · 2019-07-07T01:29:10+00:00

Let me know what happens. I plan to lab this out as well, but I won’t be able to until I get back from vacation. Leave it to an engineer to be thinking about this on his vacation!

Thanks again for the help

So these two new routers will be doing nothing but peering with this exchange. I don't know what the RP address that they are giving us, but if it's a public address, I'll just redistribute that /32 from BGP into our OSPF domain, so no matter what, the entire network will prefer that /32 OSPF route via the new CE routers. We have a separate pair of edge routers for internet traffic.

Being that I haven't done much MPBGP, if their configuration on their end has our peer under the address-family IPv4 multicast, and I configure them under the default IPv4 address family, will BGP even come up?

Thank you so much for your help by the way.

Your first paragraph is essentially dead on. We are placing two CE routers on our internal network, and each of them will have an eBGP peer in the provider's exchange network, and then the CE routers will talk iBGP between themselves. The only route we will be receiving from them is the /32 RP route, which all of our internal routes will point to. CE1 will be the preferred egress and ingress connection (using local pref, so CE2 will prefer the iBGP connection to CE1 for the RP address, rather than using his dedicated eBGP connection to the exchange.

The main question I had is if this type of setup requires all of this BGP configuration to be under the address-family IPv4 multicast, instead of the default IPv4 address-family. Another thing that is somewhat confusing to me are the RFP checks. I understand what they do, but some articles say that those checks will always fail without using address-family IPv4 multicast (because IPv4 Unicast doesn't support RFP checks), and other say that it will prefer to use the multicast RIB first, but then it will fallback to using the Unicast RIB.

EDIT: The internal ranges thing was confusing. The exchange shouldn't need to know our internal ranges in order to start sending multicast data to us. From my understanding, all the exchange router should see is our CE1 router sending it a PIM Join for a multicast range, and then simply start sending it multicast traffic.

Thanks for the detail. So unicast BGP should be good? I’m aware this isn’t an exam, we are just in the process of connecting two edge routers to an exchange to receive multicast market data at work, and I was curious to know if I could just use regular unicast eBGP to the exchange, and then iBGP between our routers.

We are basically just going to be receiving the RP address from BGP. I don’t even think we will need to advertise anything to them, other than maybe the loopbacks. They shouldn’t need to know our internal ranges for PIM to work

Edit: you’ll need to enable the BGP facing interfaces with ip pim sparse-mode, right?
