I sorry to copy the eth2's packet,that is the eth1's packet in vpp1:

I know the only way to check the mac on interface "show hardware",how could I
check the " underlying device"?
Fib entry display 17.04 not exactly correct compared to fib entry 17.01 :
17.04:
192.168.153.131/32
unicast-ip4-chain
[@0]: dpo-load-balance: [index:10 buckets:1 uRPF:9 to:[600:22840]
via:[205:9430]]
[0] [@5]: ipv4 via 192.168.153.131 host-eth1: 000c298fad61000c293129ae0800
17.01(not the same device):
192.168.190.138/32
unicast-ip4-chain
[@0]: dpo-load-balance: [index:16 buckets:1 uRPF:15 to:[9:756]]
[0] [@5]: ipv4 via 192.168.190.138 host-eth8: IP4: 00:0c:29:b7:19:20 ->
00:0c:29:57:8f:fa
Will this change affect my test results?
Thanks,

Subject: Failed to ping between two VPP
Hi Dave,
When I use stable 17.04,there is something wrong when I ping vpp2 from
vpp1,that is my configuration:
vpp1:
creat host-interface name eth1
set interface state host-eth1 up
set interface ip addr host-eth1 192.168.153.130/24
set interface mac addr host-eth1 00:0c:29:31:29:ae
vpp2:
creat host-interface name eth1
set interface state host-eth1 up
set interface ip addr host-eth1 192.168.153.131/24
set interface mac addr host-eth1 00:0c:29:8f:ad:61
then I " ping 192.168.153.131 "from vpp1,and "ping 192.168.153.130" from VPP2
the packet trace:
01:20:19:315340: af-packet-input
af_packet: hw_if_index 2 next-index 4
tpacket2_hdr:
status 0x20000001 len 60 snaplen 60 mac 66 net 80
sec 0x59196685 nsec 0x18dd5a37 vlan 0
01:20:19:315391: ethernet-input
IP4: 00:0c:29:31:29:b8 -> 00:0c:29:8f:ad:6b
01:20:19:315411: ip4-input
ICMP: 192.168.190.134 -> 192.168.190.136
tos 0x00, ttl 64, length 25, checksum 0x5a2b
fragment id 0x2259
Are you sure that this trace belongs to your pings?
Both MAC and IP address is different than one you configured….
