When interfaces are not part of VRF and below ip address config is done on these interfaces, ping with -I (interface) option, we see packets transmitting out of the right interfaces.
ip addr add 2.2.2.100 peer 1.1.1.100/32 dev enp0s3 ip addr add 2.2.2.100 peer 1.1.1.100/32 dev enp0s8 ping 1.1.1.100 -I enp0s3 , packet always goes out of enp0s3 ping 1.1.1.100 -I enp0s8, packet always goes out of enp0s8 When interfaces are enslaved to VRF as below and ip are configured on these interfaces, packets go out of one interface only. ip link add MGMT type vrf table 1 ip link set dev MGMT up ip link set dev enp0s3 up ip link set dev enp0s3 master MGMT ip link set dev enp0s8 up ip link set dev enp0s8 master MGMT ip link set dev enp0s9 up ip addr add 2.2.2.100 peer 1.1.1.100/32 dev enp0s3 ip addr add 2.2.2.100 peer 1.1.1.100/32 dev enp0s8 ping 1.1.1.100 -I enp0s3 , packet always goes out of enp0s3 ping 1.1.1.100 -I enp0s8, packet always goes out of enp0s3 Regards, Bala.
