You could use the following commands to configure: ip punt redirect [add|del] rx [<interface>|all] via [<nh>] <tx_interface> ip6 punt redirect [add|del] rx [<interface>|all] via [<nh>] <tx_interface>

Hi vijay, How to configure that features? Should I need to run the “set punt” or “ip punt redirect” command? Or should I need to do some work to make the punt work?? Thank you very much!!!

Hi One of the way I see as follows: With the recent changes I rolled up, all the TCP Packets not handled in VPP’s TCP stack would be punted via IP4/6_punt path. In the punt path, you could configure such that ip4/6_punt traffic to a specific Next hop/Interface.
