I have Openstack cluster with following environments: * 3 Controller+ 2 Compute * Interfaces example: bond0: provider network mapped to here using vlan bond0.2602@bond0: interface for overlay br-tun: 172.28.237.13/24 --> bond0.2602 attached to here --> this is overlay endpoint for Geneve.
On each compute node, I exec this command: ``` ovs-vsctl add-br br-tun ovs-vsctl add-port br-tun bond0.2602 ip addr delete 172.28.237.13/24 dev bond0.2602 ip addr add 172.28.237.13/24 dev br-tun sudo ip link set br-tun up ``` I create 2 VM ubuntu0(on compute2) and ubuntu1 (on compute3) then testing SSH between VM using private IP. It took times ~1 minutes until login prompt appear. It seams normal when pinging: ``` ubuntu@ubuntu1:~$ ping ubuntu0 PING ubuntu0 (192.168.5.187) 56(84) bytes of data. 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=1 ttl=64 time=1.13 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=2 ttl=64 time=0.968 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=3 ttl=64 time=0.911 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=4 ttl=64 time=0.567 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=5 ttl=64 time=0.645 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=6 ttl=64 time=0.602 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=7 ttl=64 time=0.635 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=8 ttl=64 time=0.380 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=9 ttl=64 time=0.640 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=10 ttl=64 time=0.523 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=11 ttl=64 time=0.907 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=12 ttl=64 time=0.725 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=13 ttl=64 time=0.574 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=14 ttl=64 time=0.724 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=15 ttl=64 time=1.16 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=16 ttl=64 time=0.947 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=17 ttl=64 time=0.457 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=18 ttl=64 time=0.428 ms 64 bytes from ubuntu0 (192.168.5.187): icmp_seq=19 ttl=64 time=1.08 ms ``` Could someone give me some hint where to start to debug or where is the issue?
