hi,all when I was trying to use vlan sub-interface as a individual L3 interface (i.e. configure an IP address in a VRF) by: namespace side(where veth_vpp1 in namespace and af_packet0 in vpp is pairwised): ip link add link veth_vpp1 name veth_vpp1.100 type vlan id 100 ip addr add 130.140.25.2/24 dev veth_vpp1.100 ip link set veth_vpp1.100 up vpp side: set interface state af_packet0 up create sub-interface af_packet0 100 set interface state af_packet0.100 up set interface ip addr af_packet0.100 130.140.25.1/24
,and then it seems that traffic gets blocking, the only way to make it work is to mannually configure mac-ip fib by: namespace : arp -s 130.140.25.1 02:fe:0d:15:17:e8 vpp: set ip arp af_packet0.100 130.140.25.2 f6:cf:5b:fc:2a:89 static I want to know how to make this work if I don't configure static mac-ip fib(i.e arp) Beacuse sometimes fetching static mac is not that easy? Thanks -- Linc @bjtu
