Hi Hongjun, Thank your very much for your support.
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?
