Catalyst 8000

Hi!

Can anyone clarify if the Catalyst 8000 SDWAN does a bonded connection ( aggregate the bandwidth of both ISP)?

Thanks

Yes, When you set default routes as

0.0.0.0/0 1.1.1.1 isp1

0.0.0.0/0 2.2.2.2 isp2

Ecmp will work

Hi,

in SD-WAN for internet connectivity you can have two or more internet connections and NAT over them. You should use either DIA route NAT or centralized policy for NAT (plus configure outside - transport interfaces for NAT).

However, with respect to overlay connection (site-to-site), if you have multiple channels, it is better to consider them as separate which still work in active/active fashion. By differentiating transport interfaces (with tunnel configuration which is called TLOC in SD-WAN), you have option to do proper Application Aware Routing, proper path selection (Traffic Engineering- TE), path control.
