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 vpp# show ip fib: 10.10.10.0/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:60 buckets:1 uRPF:64 to:[0:0]] [0] [@0]: dpo-drop ip4 10.10.10.0/24 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:59 buckets:1 uRPF:81 to:[0:0]] [0] [@4]: ipv4-glean: GigabitEthernet0/14/0: mtu:1790 ffffffffffff0008a2095a9c0806 10.10.10.1/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:62 buckets:1 uRPF:83 to:[0:0]] [0] [@2]: dpo-receive: 10.10.10.1 on GigabitEthernet0/14/0 10.10.10.255/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:61 buckets:1 uRPF:70 to:[0:0]] [0] [@0]: dpo-drop ip4 11.11.11.0/24 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:69 buckets:1 uRPF:66 to:[0:0]] [0] [@3]: arp-ipv4: via 10.10.10.2 GigabitEthernet0/14/0 linux# ifconfig vpp0 down linux# ifconfig vpp0 up linux#route -n: 10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 vpp0 vpp# show ip fib: 10.10.10.0/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:60 buckets:1 uRPF:67 to:[0:0]] [0] [@0]: dpo-drop ip4 10.10.10.0/24 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:59 buckets:1 uRPF:64 to:[0:0]] [0] [@4]: ipv4-glean: GigabitEthernet0/14/0: mtu:1790 ffffffffffff0008a2095a9c0806 10.10.10.1/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:62 buckets:1 uRPF:83 to:[0:0]] [0] [@2]: dpo-receive: 10.10.10.1 on GigabitEthernet0/14/0 10.10.10.255/32 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:61 buckets:1 uRPF:120 to:[0:0]] [0] [@0]: dpo-drop ip4 11.11.11.0/24 unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:69 buckets:1 uRPF:65 to:[0:0]] [0] [@3]: arp-ipv4: via 10.10.10.2 GigabitEthernet0/14/0
