Hi VPP Team, I'm Satomi Inoue and I belong to NTT laboratories. Could you tell me why ARP response packet is dropped?
We set up vxlan while looking at ”Using_VPP_as_a_VXLAN_Tunnel_Terminator”manual.
The procedure is as follows. [The result] ・ARP request packet : IXIA(port2)→VPP→IXIA(port1):OK ・ARP response packet : IXIA(port1)→VPP→IXIA(port2):NG→We checked it by trace command. Loopback interface in VPP drop the ARP response packet.
[set up vxlan] 1. Create sub-interface vpp# create sub-interfaces VirtualFunctionEthernet0/9/0 1 vpp# set interface state VirtualFunctionEthernet0/9/0.1 up 2. Create bridge-domain create bridge-domain 10001 learn 1 forward 1 uu-flood 1 arp-term 0 3. Create Loopback interface vpp# loopback create mac 1a:2b:3c:4d:5e:6f vpp# set interface state loop0 up vpp# set interface ip address loop0 1.1.1.1/32 vpp# set interface ip table loop0 7 4. Apply loopback interface to bride-domain vpp# set interface l2 bridge loop0 10001 bvi 5.Apply sub-interface to bride-domain vpp# set interface l2 bridge VirtualFunctionEthernet0/9/0.1 10001 0 6.Create VXLAN tunnelvpp# create vxlan tunnel src 1.1.1.1 dst 20.10.0.1 vni 10001 encap-vrf-id 7 decap-next l2
