Hi Liran,
I assume you’re using the router plugin to reflect linux routing state in VPP.
I’ve cc’d the appropriate mailer and bcc vpp-dev.
/neale.

Subject: [vpp-dev] auto-remove fib entries
Hi All, is there an option to auto-remove fib entries related to interface
after performing an administrative shutdown to the interface?
Issue example:
while configuring static route in the linux kernel and then performing
administrative down & up to the related interface the route was removed from
the linux fib but still exist in the vpp fib.
linux#ifconfig vpp0 10.10.10.1/24 up
linux#ip route add 11.11.11.0/24 via 10.10.10.2
linux#route -n:
10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 vpp0
11.11.11.0 10.10.10.2 255.255.255.0 UG 0 0 0 vpp0
