[c-nsp] GRE tunnel issue - ASR 903

[Mouniri Md]

Hello all,

I tested gre tunnel on a ASR 903 and I have slow speed (less than 10Mbps) when doing some iperf test whereras when gre tunnel is not used I can reach the wire speed.
I tried to play with the mtu without success.

Do someone have already experiencing this? It looks like that gre trafic is handled in cpu and not in hard, but I cannot find any documentation explaining this.

Thank you for your help.

Regards,
Mouniri
