Hi, I am trying to test vpp load balance for my scenario. I create two pairs of veth on host linux, and connect vpp and two Nginx containers by them. A physical NIC is used by VPP as eth0 , and I create a loopback interface (loop0), finally I add the two host-interfaces and the loopback interface in the same bridge domain. the network toplogic is just like this picture. I can ping vpp eth0 within container. I hope the traffic from external can reach the nginx containers.
Then I would like to enable the vpp load balance feature, the configuration is like this: set interface state eth0 up set interface mtu 1500 eth0 set interface ip address eth0 10.161.30.5/24 ip route add 0.0.0.0/0 via 10.161.30.1 create host-interface name vpp1host create host-interface name vpp2host set interface state host-vpp1host up set interface state host-vpp2host up create loopback interface set interface state loop0 up set interface mtu 1500 host-vpp1host set interface mtu 1500 host-vpp2host set interface mtu 1500 loop0 create bridge-domain 1 set interface l2 bridge host-vpp1host 1 set interface l2 bridge host-vpp2host 1 set interface l2 bridge loop0 1 bvi set interface ip address loop0 2.2.2.1/24 lb conf ip4-src-address 2.2.2.1 lb vip 10.161.30.5/32 protocol tcp port 80 encap nat4 type clusterip target_port 80 lb as 10.161.30.5/32 protocol tcp port 80 2.2.2.10 2.2.2.20 lb set interface nat4 in loop0 (after I add this configuration, the loop0 interface can not reach container). DBGvpp# show lb vips verbose ip4-nat4 [1] 10.161.30.5/32 new_size:1024 protocol:6 port:80 type:clusterip port:20480 target_port:80 counters: packet from existing sessions: 0 first session packet: 0 untracked packet: 0 no server configured: 0 #as:2 2.2.2.20 512 buckets 0 flows dpo:18 used 2.2.2.10 512 buckets 0 flows dpo:17 used ----------------------------------------------------------------------------------------------------------------------------------------------- By the way,I also tried nat44 static mapping, and it works. nat44 add address 10.161.30.5 set interface nat44 in loop0 out eth0 nat44 add load-balancing static mapping protocol tcp external 10.161.30.5:80 local 2.2.2.10:80 probability 50 local 2.2.2.20:80 probability 50 So , can any one check where is the problem?
