Hello, I need to configure proxy-arp in VPP, but it seems doesn't work in my case. 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 connected to VPP interface 0/8/0 with IP 10.0.1.0/24 host B with IP 10.0.2.2/8 connected to VPP interface 0/9/0 with IP 10.0.2.0/24 The VPP config: set interface ip address GigabitEthernet0/8/0 10.0.1.1/24 > set interface ip address GigabitEthernet0/9/0 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. > From 10.0.2.2 icmp_seq=1 Destination Host Unreachable > From 10.0.2.2 icmp_seq=2 Destination Host Unreachable > From 10.0.2.2 icmp_seq=3 Destination Host Unreachable > From 10.0.2.2 icmp_seq=4 Destination Host Unreachable > From 10.0.2.2 icmp_seq=5 Destination Host Unreachable > From 10.0.2.2 icmp_seq=6 Destination Host Unreachable --- 10.0.1.2 ping statistics --- > 9 packets transmitted, 0 received, +6 errors, 100% packet loss, time 8190ms VPP version 19.04. OS: Linux 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux Thanks a lot in advance. Regards, Aleksander
