tunnel route-via

Hello,
It's nice to meet you in the community.
We're working on your problem. Please be patient.

Hello,

The document supports configuring the interface in mGRE mode. Did you report an error when you entered the tunnel route-via GigabitEthernet 0/0/1 mandatory command?

merci

Hi, 

I have checked the product documentation, in V200R009 and later versions, you can run the tunnel route-via command to specify the routing outbound interface for a mGRE tunnel.
The destination IP address of a GRE tunnel interface is manually configured, whereas the destination IP address of an mGRE tunnel is resolved by the next hop resolution protocol (NHRP). An mGRE tunnel interface has multiple remote ends because there are multiple GRE tunnels on the interface. 

 And the DSVPN function requires a license, So I guess you can't use this command because of license restrictions.

You are advised to contact TAC for confirmation.
