Assuming this isn't some silly troll, you need to either hire someone with a bit more clue or see if your provider is willing to configure your router. It sounds like you have no idea how IP routing works.

Yeah, we're using it for an anycasted node but like, I'm confused on
certain parts like, just a really basic question.
When doing things like

conf t
router bgp AS1337

neighbor 208.54.128.0 remote-as AS13335
neighbor 208.54.128.0 description BGP with Upstream
neighbor 208.54.128.0 password "lolpass"

address-family ipv4
no synchronization
neighbor 208.54.128.0 activate
neighbor 208.54.128.0 soft-reconfiguration inboung

I'm confused on when doing this, would I need to state like

First go to AS13335 then go to TATA then go to my server or would it just
automatically do that or would my provider do that? I'm confused on that.
how would I state multiple peers.....?

An Anycasting node. For example, as part of a reliable DNS service.
A /24 is usually the smallest prefix length that is portably accepted.

Also, applications where connections need to appear to be coming from many
source IPs.

A single linux box with a whole /24 on it? What sort of use case is that,
BTW?

I know, the DC is going to be giving me a BGP session on their router

can set it up, I'm not using a Linux server as a router.

Howdy,

Unless you have (1) a real router available, not a just a server and
(2) an expert available to help you with your first BGP configuration
I strongly recommend you simply ask your service provider to announce
the /24 to the Internet on your behalf.

Server-based BGP software like Quagga for Linux is reasonably good but
it should absolutely not be involved in your _first_ attempt to
connect with the Internet's default-free zone. Simple mistakes with
eBGP can cause tremendous damage to other folks on the Internet. Trial
and error is simply not OK. If it isn't worth it to you to buy a
BGP-capable router then you also aren't prepared to make the
investment in learning it takes to use BGP without causing harm.

Bill Herrin
