When we were reviewing sd-wan solutions from a number of vendors last year -my recollection is that hub and spoke or dual hub and spoke (but not multi-hub and spoke) was their go to topology and most of them didn't even considered full-mesh of tunnels between spoke sites until I asked.
If you consider what sd-wan is selling, its MPLS like QOE over cheapo Internet links - for which they need at least two (ideally more) links, then the number of tunnels is going to be n(n-1)/2 times the number of cheapo links to the spoke site. adam _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
