Hi Vishal, I think when the interface goes down to change the MAC address, the routes will go away. The only way to to make sure the routes will be restored is to change the initialization order. In your case, br0 is initialized first, then dpdkbond0 which will cause the issue. The order is alphabetical, so try renaming br0 to something like zbr0 to see if the bridge is reconfigured with the routes. fbl > Steps to reproduce the issue: > > # Create the bridge in OVS. > $ ifup br0 > > # Dump the routes > $ ip route > 11.2.0.0/24 dev br0 proto kernel scope link src 11.2.0.26 > 100.100.100.10 via 11.2.0.202 dev br0 > 100.100.100.20 via 11.2.0.201 dev br0 > 169.254.0.0/16 dev br0 scope link metric 1036 > > # Add DPDK Bond to bridge br0 > $ ifup dpdkbond0 > > # Dump the routes > $ ip route > 11.2.0.0/24 dev br0 proto kernel scope link src 11.2.0.26 > --> Other routes for br0 are missing. > > Here are the ifcfg files for the bridge BR0 and DPDKBOND0 port along with > static routes. > ============================================= > $ cat ifcfg-br0 > DEVICE=br0 > ONBOOT=yes > HOTPLUG=no > NM_CONTROLLED=no > PEERDNS=no > DEVICETYPE=ovs > TYPE=OVSUserBridge > BOOTPROTO=static > IPADDR=11.2.0.26 > NETMASK=255.255.255.0 > OVS_EXTRA="set bridge br0 fail_mode=standalone" > > $ cat ifcfg-dpdkbond0 > DEVICE=dpdkbond0 > ONBOOT=yes > HOTPLUG=no > NM_CONTROLLED=no > PEERDNS=no > DEVICETYPE=ovs > TYPE=OVSDPDKBond > OVS_BRIDGE=br0 > BOND_IFACES="dpdk0 dpdk1" > OVS_OPTIONS="bond_mode=balance-tcp other_config:lacp-time=fast lacp=passive" > > $ cat route-br0 > 100.100.100.10 via 11.2.0.201 dev br0 > 100.100.100.20 via 11.2.0.202 dev br0 > > ============================================= > > Warm Regards, > Vishal > > _______________________________________________ > discuss mailing list > disc...@openvswitch.org > https://mail.openvswitch.org/mailman/listinfo/ovs-discuss -- Flavio _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
