ospf and external bgp?
following questions
- If a router has two interfaces in an autonomous network, say AS200,
OSPF is bound to these interfaces, the 3rd interface speaks via BGP
With the AS300, how do you bind interfaces 1-3 to the corresponding protocol? It would be nice if you could provide the commands under Cisco.
You should define your requirements more accurately.
But apart from that, I assume that you have hardly any experience in this, and neither with the hardware you want to use.
But how do I interpret this now you want to redistribute in BGB?
Remember that you should give you more knowledge, first of all, because you can break a lot with that.
but it helps a little https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/5242-bgp-ospf-redis.html
Thank you. link

OSPF is not talking about autonomous systems, but areas.
So in this case the interfaces are 1-2 yes in the same OSPF area.
The third interface is with BGP with the other AS, so that then via eBGP, since the counterpart is another AS.
This router is also the ASBR of the OSPF network. The networks to be known are then transferred from the OSPF to the BGP and thus transferred to the BGP neighbors. This usually as a route summary.
