Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1376446 Title: Neutron LBAAS agent ignores MTU settings used by subnets Status in neutron: Expired Bug description: The network interfaces in qlbaas namespaces always use 1500 as their default MTU setting. This may cause trouble when communicating with instances that have different MTU set (usually through dhcp options using /etc/neutron/dnsmasq-neutron.conf). Different MTU values may break communications between instances and load balancers and lead to weird behaviours, such as some web pages timing out waiting for a reply while others work. Manually setting an lbaas namespace to the same value as the instance corrects any communication problems between balancer and instance. Neutron should use options from their subnet or at least provide a way to manually set the load balancer's MTU. For reference, here is the output of a lbaas namespace settings showing MTU 1500: # ip netns exec qlbaas-a38fc742-9c0b-4503-a0b9-64d5a6adfe77 ip a (...) 234: tape853dd58-66: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default link/ether fa:16:3e:a2:e0:c7 brd ff:ff:ff:ff:ff:ff inet 10.134.54.151/22 brd 10.134.55.255 scope global tape853dd58-66 valid_lft forever preferred_lft forever inet6 fe80::f816:3eff:fea2:e0c7/64 scope link valid_lft forever preferred_lft forever To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1376446/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
