The topology is as below. br0(192.168.100.10)----> vnet0 -----> dpdk(NIC1- e1000)------->dpdk(NIC2-e1= 000)------>vnet1----->br1(192.168.100.20) I am sending ARP packet from br0 using PackETH tool destined to br1. I have=A0 edited the dpdk l2fwd code in such a way that , the destination i= s broadcast address(ffff). In br1 , i can see the arp resquest, but the host bridge is not responding = for the arp request. In br1: =3D=3D=3D=3D=3D tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on br1, link-type EN10MB (Ethernet), capture size 65535 bytes 12:21:15.459667 ARP, Request who-has 192.168.100.20 (00:0a:e7:2c:44:2b (oui= Unknown)) tell 192.168.100.10, length 46 12:21:15.651610 ARP, Request who-has 192.168.100.20 (00:0a:e7:2c:44:2b (oui= Unknown)) tell 192.168.100.10, length 46 12:21:15.867692 ARP, Request who-has 192.168.100.20 (00:0a:e7:2c:44:2b (oui= Unknown)) tell 192.168.100.10, length 46 In l2fwd application example also, the arp packets are getting received on = the adjacent ports, but the arp reply has not been sent back from br1. Could you please let me know how to make the host(br1) to reply the arp req= uest.
