I have tried this configuration for UDP packets and below is my configuration classify table mask l3 ip4 proto classify session l2-input-hit-next input-node nsh-classifier table-index 0 match l3 ip4 proto 17 opaque-index 47615 set int l2 bridge GigabitEthernet0/9/0 1 1 set interface l2 input classify intfc GigabitEthernet0/9/0 ip4-table 0 When i send a UDP packet, the packet reaches till "l2-input-classify" and goes to "l2-learn" node. How can i direct the packet to "nsh-classifier" node?

I have few queries. 1. I would like to know what is the configuration for IP4 traffic to reach the nsh-classifier node in VPP using vppctl ? I am trying with the following command for redirecting ip4 traffic to nsh-classifier node. But the command throws error: "Table index required" classify table mask l3 ip4 proto classify session hit-next input-node nsh-classifier table-index 0 match l3 ip4 proto 17 opaque-index 47615 -- This command throws error 2. Do i need to associate interface with classifier table created? Thanks in advance :) -- Thanks & regards, Phaneendra Manda.
