Ring of Edge nodes supported?

[Sylvain_Che]

Hello,

Is such topology supported in SDA? Any official documentation?
(Access switches defined as Edge nodes, not as Extended nodes. All links configured as Layer3).

If yes, any pros or cons you might think of?

Thanks,
Sylvain.

Yes, this is supported - SDA supports any underlay topology as long as routing for loopback addresses is in place. I would however aim to have a more traditional topology if possible where your edge nodes either have redundant links to a distribution switch or to the border/control-nodes depending on your topology size. The main benefit of going with such a topology is redundancy.

as @Torbjørn said it's supported by routed architecture natively. & personally i have no
concerns about ring vs star, star vs mesh etc routed topologies as soon as redundancy, throughput & all LISP/VXLAN requirements are addressed.

BTW here is a glitch in the page's code:

Edit

Sorry, Torbjorn , i'm blameless :0)

LOL! I actually didn't notice it when I first read your post.
