DMVPN site to site tunnel?

Dear All,

This  is regarding the DMVPN using mGRE. I want to know that spoke to spoke  traffic passes through hub or it will create the direct tunnel between  spoke to spoke?

Thank You,

DMVPN site to site tunnel?

depending on your design you can forces all spoke to spoke traffic to go to the hub OR

spoke to spoke traffic can build dynamic tunnels between each other

the later is a very nice design that does not require each spoke to know about other spokes ahead of time

i more often though prevent this. i require all spoke traffic to transit the hub. i do this when spokes require inet access. This allows me to have a more robust control access to the inet. if you allow spokes to access through a split tunnel arangement, you risk a spoke being infected, a tougher job controlling each spoke, more work looking at numerous log and access files and worse, a bad spoke infecting other sites.

play it safe, controll access the the inet from a single source
