DVTI and SVTI??

[abhi-adte]

Hi,

What is DVTI and SVTI and where it can use in DMVPN??

You should post this in the vpn forum - plenty of experts there to help as those are all VPN technologies.

But basically VTI is ipsec using tunnel interfaces *without* GRE.  DMVPN uses GRE, so VTI can't be used in DMVPN (though there are other dynamic VTI solutions).

You can read more about VTI here:
