*Hi,*
13.0.0.200 -------------------------------|GigabitEthernet1/0/0 (plain
interface)13.0.0.2
|
GigabitEthernet1/0/0.111(vlan interface)13.0.0.5 packet to send out
destination IP (13.0.0.200)
Fig 1.
I am trying to configure two IP’s belonging to same subnet on plain and a
VLAN interface(refer fig 1).While sending a packet, the ip4-lookup node is
fetching the dpoi_index pertaining to the VLAN interface which in-turn
gives the software index to VLAN interface in lookup.
If I try same scenario on Linux ,ping to the same destination IP(IP:
13.0.0.200) works as kernel pick up the plain interface route since that is
the 1st route in its routing table.
*FIB table entry: *

UNRESOLVED
Questions :
1. Is there any specific reason why VPP always returns last entry added for
that prefix instead of 1st entry? Can Vpp behaviour be made similar to
Linux kernel Behaviour?
