Hi to all,
I have a compagny which want to move from cisco to mikrotik
But with their cisco infrastructure they have implemented DMVPN which permit to them to create dynamic tunell

How can I implement something similar on routerOS

Regars

MikroTik supports the basic components that make up a DMVPN network... Notably,

- GRE tunnels (see the "/interface" menu)
- IPsec (see the "/ip ipsec" menu)
- OSPF, RIP and BGP are all supported (see the "/routing" menu and its submenus)

I don't know about "NHRP", unless that's just "basic routing" we're talking about, in which case, see "/ip route".



The only "problem" for DMVPN in MikroTik is that, at least to my limited knowledge, there isn't a trivially easy way to pull it all together, as supposedly Cisco can (I haven't tried doing such a thing with them either, so I can't say for sure...). You need to configure the individual components, for them to eventually achieve the same effect.

How can I do ? now

Please I need help

You can't. The components are there, but not the management. And dmvpn is all about the management.

A wild (and un-educated) guess: could possibly Mesh be an option for you?
