Please don’t SHOUT by capitalizing; especially in a case like this which
amounts to trying (unsuccessfully) to put two interfaces on the same subnet.
What this trace actually shows is that the dhcp client received two addresses.

'show int address' does not show ip on second interface:

Subject: [vpp-dev] Not getting DHCP ip on second DPDK interface
Hi,
I created two DPDK interface on ubuntu VM and setting them to DHCP client. But
only one interface gets DHCP IP.
1. BGvpp# show int
Name Idx State MTU (L3/IP4/IP6/MPLS)

Also noticed that ping to Internet works only until first interface gets IP
address. The moment the second interface is set to DHCP Client, ping stops
working.
