Traffic Engineering in SDA

[fatalXerror]

Hello!

I have 4x fabrics with 2x of it have server farm block and internet block, all fabric sites are connected via dark fiber using SD-Access Transit.

How can I achieve that the 2x fabric sites go to server farm A and internet block A and the other 2x fabric sites go server farm B and internet block B so that both of my server farms and internet blocks will be somehow active/active.

Thanks

This could be a good use case for Border Affinity attributes (fabric sites with deterministic Internet access borders)

Hi @jalejand , thanks for the feedback but I think the affinity ID will not be able to achieve what I am trying to do.

basically, i just want to direct the traffic of my fabric A & B to my Shared Services X and fabric C & D to my Shared Services Y.

How are fabric A&B reaching SSX?

And C&D reaching SSY?

Each fabric has an IP transit while using SDA Transit? A simple diagram could help
