BGP Attribute Categories

There are four categories of BGP attributes:

Well-known mandatory:Recognized by all BGP peers, passed to all peers, and present in all Update messages. Well-known mandatory attributes include:- Next-hop- Origin- AS PATH

Well-known discretionary:Recognized by all routers, passed to all peers, and optionally included in the Update message. Well-known discretionary attributes include:- Local Preference- Atomic Aggregate

Optional transitive:Possibly recognized by BGP routers and passed to BGP peers. Optional transitive attributes are marked as partial when not recognized. Optional transitive attributes include:- Aggregator- Community

Optional non-transitive:Possibly recognized by BGP routers but not passed to peers. Optional non-transitive attributes include:- Multi-exit discriminator (MED)- Originator ID- Cluster-ID

The three well-known mandatory BGP attributes that must be present in every BGP update message are:

Next Hop: Indicates the next hop IP address to reach the advertising BGP peer.

Origin: Indicates how the route was originated, whether it was via IGP, EGP, or incomplete.

AS Path: Lists the autonomous systems that the update has traversed.

Yeah, and I believe NEXT_HOP is also mandatory. It shows the next router.

I think AS_PATH is definitely one of them. It's crucial for routing.

I feel like I should know this! AS Path and Next Hop sound right, but I’m struggling to recall the third mandatory attribute. Was it something like Community?

I practiced a similar question last week! I’m pretty confident about AS Path and Next Hop, but I keep mixing up the third one. Is it Multi-Exit Discriminator?

I remember studying BGP attributes, and I think AS Path and Next Hop are definitely mandatory. The third one... could it be Origin?

I think the mandatory BGP attributes include AS Path, Next Hop, and maybe Local Preference? I'm not entirely sure about Local Preference though.

Okay, mandatory BGP attributes... I'm pretty sure Origin, AS_Path, and Next_Hop are some of the main ones, but I'll double-check my notes to be sure.
