Fabric domains vs mutiple sites in one fabric domain

[markus.forrer]

Hi community

Can someone explain we the pro and cons.

One Company with multiple sites. Multiple Fabric Domains or One Fabric Domain with multiple sites?

Each site has his own wlc and border and control-plan note. All sites has ip based handoff.

Is there something to consider?

Hi Markus,

Fabric domain is mainly for different Administrative/policy domains.

For one company with multiple sites, you should stick to single Fabric domain. This is the most commonly deployed scenario.

The transit can be ip transit or SD-Access transit. It does not matter for picking fabric domain.

For quicker response pls post SD-Access queries to  SDA Community  (http://cs.co/sda-community)

• Fabric domain is for different Administrative/policy domains.In the fabric domain, the control-plane device acts as the map-server and the map-resolver. Enables the control-plane device with IPv6 LISP map resolver capabilities.
• For multiple sites in one Fabric domain is generally what you see deployed. But choosing one is your choice.
• ip transit/SD-Access transit are two transit flavors. You can pick your choice what you want.
