Please help me to understand the mistake. In classic Proxy-ARP test scheme I have 2 clients and one VPP host as a router. host A with IP 10.0.1.2/8<http://10.0.1.2/8> connected to VPP interface 0/8/0 with IP 10.0.1.0/24<http://10.0.1.0/24> host B with IP 10.0.2.2/8<http://10.0.2.2/8> connected to VPP interface 0/9/0 with IP 10.0.2.0/24<http://10.0.2.0/24> The VPP config: set interface ip address GigabitEthernet0/8/0 10.0.1.1/24<http://10.0.1.1/24> set interface ip address GigabitEthernet0/9/0 10.0.2.1/24<http://10.0.2.1/24> set interface state GigabitEthernet0/8/0 up set interface state GigabitEthernet0/9/0 up set interface proxy-arp GigabitEthernet0/8/0 enable set interface proxy-arp GigabitEthernet0/9/0 enable set ip arp proxy 10.0.1.2 - 10.0.1.2 set ip arp proxy 10.0.2.2 - 10.0.2.2 vpp# show ip arp Time IP4 Flags Ethernet Interface 81.3389 10.0.1.2 D 08:00:27:a2:18:38 GigabitEthernet0/8/0 89.8343 10.0.2.2 D 08:00:27:8c:94:29 GigabitEthernet0/9/0 Proxy arps enabled for: Fib_index 0 10.0.1.2 - 10.0.1.2 Fib_index 0 10.0.2.2 - 10.0.2.2 When I try to ping one client host from another one I see shch result: PING 10.0.1.2 (10.0.1.2) 56(84) bytes of data.
