Hi Matthew, According to the information that you gave us, we run the below configuration : VPP version : 23.02-rc0~219-g6903da2
set int ip address TwentyFiveGigabitEthernetd8/0/0 10.20.10.22/24 set interface state TwentyFiveGigabitEthernetd8/0/0 up create interface memif id 0 master set int ip address memif0/0 10.10.1.1/24 set int state memif0/0 up create interface memif id 1 master set acl-plugin acl permit src 0.0.0.0/0 dst 10.20.10.22/32 proto 0-255 sport 0-65535 dport 0-65535 abf policy add id 0 acl 0 via 10.10.1.1 memif0/0 abf attach ip4 policy 0 TwentyFiveGigabitEthernetd8/0/0 Even though adding memif0/0 interface as next hop, the output of "show abf attach" command is shown as dpo-drop ip4 . DBGvpp# show abf attach TwentyFiveGigabitEthernetd8/0/0 ipv4: abf-interface-attach: policy:0 priority:0 [@1]: dpo-drop ip4 As you can see in the trace log below, after abf-input-ip4, the packet enters ip4-drop but we expect to see memif-input node instead of ip4-drop . Is there anything missing on the above configuration?
