my question is I have hub and spoke topology for 400 branches, vMX-Meduim-Azure, the max are 250 site-to-site VPN
each branch with two wan links, so if I need to configure each group of spokes that will be 50 per group, for simplicity lets focus on group 1 (50 spokes) and Group 2 (50 spokes)
group1 will be configured as spoke (add two hubs, hub1 then hub2), that mean 100 vpn tunnels per hub
group 2 will be configured same as spoke ( add two hubs, hub2 then hub1), that mean 100 vpn tunnels per hub
the total number for each hub is 200 vpn tunnels
my two questions are:
1- adding two hubs means tunnels will be established from spokes to hubs but only traffic will be preferred based on hubs order, right?
2- is there any better solution as now I need to have 8 vmxs for only 400 branches
