Great university level information on those but, OSI of IETF? No corporation cares. I´m so incredibly grateful to you for doing these videos. You literally are positively affecting the quality and sanity of my life, and many others. I hear Patreon pays well.

Hello. With all due respect. Let me quote from the Cisco community forum: "Speaking of next-hop for link state protocols is not appropriate and it can be misleading. The next-hop in OSPF or IS-IS is not the device from which the prefix was received but it is the device on the best path to destination." I totally agree with that

Great explanation. You mentioned that these connections will have the same subnet then you said that most probably this connection will be via WAN which is true and we know that you can not get WAN links with the same subnets in different locations. I think you must mention interface tunnels or something similar that will allow having the same subnets over the WAN.
@PracticalNetworking
2 жыл бұрын
Whether you're using interface tunnels, or have something sorted with an ISP is somewhat beyond what I wanted to get into for this video (since it isn't a WAN video as much as an OSPF network types video). Generally, if the IPs at each WAN site are *not* the same, then you'd likely have a collection of Point to Point networks, as I mentioned in the video =). Cheers.

Would there be any practical advantage in using the (non-default) configuration of point-to-point ospf network type for point to point ethernet links between two routers, instead of the (default) broadcast network type?
@PracticalNetworking
2 жыл бұрын
Manually setting them as Point to Point spares you from the DR election, and therefore the WAIT timer to see if a DR already exists. So the link will come up and adjacencies will go to to FULL quicker.

Thanks for making such an informative videos. Your last comment shanked my concept about ospf where you said ospf is rarely used in wan these days. According to my understanding with in any autonomous system ospf provides routing between many many routers and obviously this autonomous system could be intercontinental. Only inter autonomous Communication triggers bgp. Even mpls service providers that might be continental use ospf between their routers according to my knowledge. Can you clear this up to me.

As usual, excellent, clear, and well illustrated content! 👍 Thanks, Ed. It isn't totally clear to me still, though, as far as the NBMA manual config of neighbor IP. In the example, you said, ' on R2, manually config the IP of R4, and that will prompt a response from R4...'. 1) doesn't that (manual config) sort of defeat the purpose of OSPF, or does it maintain adjacency on its own via LSUs after init discovery? And 2) how would you manually config R4 address on R2, thru an IP OSPF statement ? (I forget exactly the command, but it's more specific than a network statement). As for the 'conundrum' of the next hop on a P2MP design, I assumed it would be the hub (so that felt good to get right 😄) , but, yeah, the manual config bit "throws me" a little. As always, thanks so much for such awesome content, and I'll share it as far as I can.
@PracticalNetworking
2 жыл бұрын
Good questions! 1. Yes, maintaining the neighborship _after_ the manual IP configuration is done automatically. The manual configuration just solves the problem of "how do we discover if another OSPF router is on this link." 2. The command is simply: "neighbor x.x.x.x" inside the OSPF process =) Congrats on solving the Conundrum of Next Hop IP on P2MP.

Thank you for the great lessons. As with the hub topology, how would that be wired in an actual real-life situation? If you have a router connected to two or more routers in a hub and spoke topology, would a serial or ethernet cable with multiple branches be used? In other words, in the hub diagram you have, how do the three cables to R2, R3, and R4 merge together? Do they meet in an actual hub? Or the cables simply go from one strand to three strands?
@PracticalNetworking
2 жыл бұрын
Glad you've enjoyed it. Hub/Spoke is more of a WAN concept. So it isn't physical connectivity connecting the devices. It's a cable from each location's Edge router that connects to an ISP, and the ISP does some "WAN Magic" to interconnect the different branches. So it isn't _physically_ a Point to Multipoint link, it's _logically_ a point to multipoint link.
