Hi Everyone, I would like to use vpp classifier to classify the packet (l3 ip4 src & dst, l4 port) and deliver to desired destination by defined rules.
1. iPerf traffic (vpp1) -------memory interface-----> vpp2 2. vpp2 classify the src port of the traffic. src port 12300 goes to TAP 0, src port 12399 goes to vpp3 via memif 0/3 Topology as below, Packet dropped in vpp2 & not going anywhere.. Trace as below Packet 1 00:04:30:392423: memif-input memif: hw_if_index 2 next-index 4 slot: ring 0 00:04:30:392444: ethernet-input IP4: b2:5f:84:5e:0b:43 -> 9e:db:96:ff:25:fa 00:04:30:392460: error-drop rx:memif0/2 00:04:30:392462: drop ethernet-input: l3 mac mismatch vpp# show ip fib ipv4-VRF:0, fib_index:0, flow hash:[src dst sport dport proto ] locks:[src:plugin-hi:2, src:default-route:1, ] 0.0.0.0/0 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:1 buckets:1 uRPF:0 to:[0:0]] [0] [@0]: dpo-drop ip4 0.0.0.0/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:2 buckets:1 uRPF:1 to:[0:0]] [0] [@0]: dpo-drop ip4 10.10.2.0/24 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:22 buckets:1 uRPF:20 to:[0:0]] [0] [@12]: ip4-classify:[0]:table:0 10.10.2.1/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:21 buckets:1 uRPF:19 to:[0:0]] [0] [@3]: arp-ipv4: via 10.10.2.1 memif0/2 224.0.0.0/4 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:4 buckets:1 uRPF:3 to:[0:0]] [0] [@0]: dpo-drop ip4 240.0.0.0/4 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:3 buckets:1 uRPF:2 to:[0:0]] [0] [@0]: dpo-drop ip4 255.255.255.255/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:5 buckets:1 uRPF:4 to:[0:0]] [0] [@0]: dpo-drop ip4 ipv4-VRF:100, fib_index:1, flow hash:[src dst sport dport proto ] locks:[src:classify:1, ] 0.0.0.0/0 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:9 buckets:1 uRPF:7 to:[0:0]] [0] [@0]: dpo-drop ip4 0.0.0.0/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:10 buckets:1 uRPF:8 to:[0:0]] [0] [@0]: dpo-drop ip4 10.10.2.2/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:19 buckets:1 uRPF:17 to:[0:0]] [0] [@3]: arp-ipv4: via 10.10.2.2 memif0/3 224.0.0.0/4 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:12 buckets:1 uRPF:10 to:[0:0]] [0] [@0]: dpo-drop ip4 240.0.0.0/4 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:11 buckets:1 uRPF:9 to:[0:0]] [0] [@0]: dpo-drop ip4 255.255.255.255/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:13 buckets:1 uRPF:11 to:[0:0]] [0] [@0]: dpo-drop ip4 ipv4-VRF:200, fib_index:2, flow hash:[src dst sport dport proto ] locks:[src:classify:1, ] 0.0.0.0/0 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:14 buckets:1 uRPF:12 to:[0:0]] [0] [@0]: dpo-drop ip4 0.0.0.0/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:15 buckets:1 uRPF:13 to:[0:0]] [0] [@0]: dpo-drop ip4 10.10.2.2/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:20 buckets:1 uRPF:18 to:[0:0]] [0] [@3]: arp-ipv4: via 10.10.2.2 tap0 224.0.0.0/4 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:17 buckets:1 uRPF:15 to:[0:0]] [0] [@0]: dpo-drop ip4 240.0.0.0/4 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:16 buckets:1 uRPF:14 to:[0:0]] [0] [@0]: dpo-drop ip4 255.255.255.255/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:18 buckets:1 uRPF:16 to:[0:0]] [0] [@0]: dpo-drop ip4
