wondra | Dear people of Neutron, I come from Pure Storage with a netowrking problem. We have a few clusters of OpenStack for testing of software for our storage arrays. We use mainly provider networks with MTU 9000. Someone has created a tenant network with MTU 1450 and put some instances on it. That broke our provider network, because both these networks met in OpenVSwitch br-int which promptly lowered | 14:20 |
wondra | its MTU to 1450. Is there any way for there networks to coexist? Also, the documentation suggests that there can be multiple physical networks with multiple MTU settings. Won't that hit the same problem? | 14:20 |

slaweq | wondra: mtu of br-int interface doesn't really matter | 14:40 |
slaweq | wondra: this interface isn't really used for anything | 14:41 |
wondra | The symptom was that new instances didn't get metadata. The packet was 1800 bytes long and it got eaten on br-int near the neutron-dhcp-agent namespace. | 14:41 |
slaweq | wondra: I really don't think it was due to that mtu | 14:42 |
slaweq | You can of course manually set mtu on br-int to some higher value if You need | 14:42 |
slaweq | but I think that problem is somewhere else | 14:42 |
wondra | An OpenVSwitch bridge has the MTU of its smallest port: https://serverfault.com/questions/680635/mtu-on-open-vswitch-bridge-port | 14:43 |
slaweq | wondra: yes, but this port isn't used to send any packets reallyt | 14:43 |
slaweq | *really | 14:44 |
slaweq | this topic was raised couple of times already e.g. in Launchpad | 14:44 |
wondra | The br-int port itself is not a problem. But the bus of OpenVSwitch has an intrinsic MTU. | 14:44 |
slaweq | wondra: I don't think so | 14:45 |
wondra | They talk about "the current bridge minimum" https://docs.openvswitch.org/en/latest/faq/issues/ | 14:45 |
slaweq | if Your tap interfaces has got correct mtu then it should works | 14:45 |
*** ociuhandu has quit IRC | 14:51 | |
wondra | If you'd like something from Launchpad, this bug is identical to ours. Their suggestion to investigate MTU helped me pinpoint the root cause: https://bugs.launchpad.net/cloud-init/+bug/1837927 | 14:58 |
openstack | Launchpad bug 1837927 in cloud-init "Missing mandatory path: http://169.254.169.254/openstack/2018-08-27/meta_data.json" [Undecided,Invalid] | 14:58 |

ralonsoh | ygk_12345, hi | 16:30 |
ygk_12345 | ralonsoh need some info | 16:31 |
ralonsoh | sure | 16:31 |
ygk_12345 | ralonsoh in the case of external provider networks, how would the physical external network switch know that a specific pool of ips from its subnet have been assigned to vms on openstack ? | 16:32 |
openstackgerrit | Rodolfo Alonso proposed openstack/neutron master: Ensure "keepalived" is correcly disabled https://review.opendev.org/c/openstack/neutron/+/766939 | 16:33 |
ralonsoh | ygk_12345, no idea directly | 16:34 |
ralonsoh | you can list the ports for a network and list the IPs assigned | 16:34 |
ralonsoh | openstack port list --network private | 16:35 |
ralonsoh | openstack port list --network private -c fixed_ips -f value | 16:35 |
ralonsoh | or are you talking about a subnet pool? | 16:35 |
ralonsoh | sorry, maybe I don't understand the question | 16:36 |
ralonsoh | but I think you are talking about the IPs, not the subnet pool | 16:36 |
ygk_12345 | ralonsoh thats not my question | 16:36 |
ygk_12345 | ralonsoh if we ping the floating ip from outside, how would the physical switch responsible for the external provider network know that a particular pool of ips from its network have been assigned to a vms | 16:37 |
admin0 | ygk_12345, openstack runs its own DHCP service | 16:37 |
ralonsoh | ok, so you are talking about FIPs | 16:38 |
ygk_12345 | yes | 16:38 |
admin0 | and that particular ip is assigned | 16:38 |
admin0 | if you have that ip somwhere else, it will be a conflict | 16:38 |
ralonsoh | when a FIP is assigned, a GARP is sent | 16:38 |
ralonsoh | to make public the MAC of this IP | 16:38 |
openstackgerrit | Merged openstack/neutron master: Handle router HA port concurrently deleting https://review.opendev.org/c/openstack/neutron/+/764913 | 16:38 |
ralonsoh | maybe this could be the method for this switch to read that | 16:38 |
ygk_12345 | ralonsoh thats what I am asking | 16:39 |
admin0 | ygk_12345, its a basic arp request | 16:39 |
admin0 | not from the switch, but from the router | 16:39 |
ygk_12345 | does that GARP reach the devices on the physical switch as well ? | 16:39 |
ralonsoh | it must reach it | 16:39 |
admin0 | the router sends an arp saying who has x.y.z.IP and it replies | 16:39 |
ralonsoh | because this is the goal | 16:39 |
ralonsoh | to make this IP (the FIP) publicly known | 16:39 |
ralonsoh | the GARP is sent in the FIP subnet broadcast domain | 16:40 |
ygk_12345 | admin0 so when the request for a FIP comes from outside, the switch forwards it to the router right ? | 16:42 |
admin0 | no | 16:43 |
admin0 | the switch is just a dump switch | 16:43 |
admin0 | its a medium in between | 16:43 |
admin0 | let me explain | 16:43 |
admin0 | when you ping from your home to your instance, via routing and BGB in internet etc.. the packet reaches your .1 gateway .. ( the datacenter router) .. which may have 1 or more switch connected to it .. say you are doing a ping for .10 .. now this .1 router will send an arp request saying .. who has x.x.x.10 .. reply .1 at (mac address) | 16:44 |
admin0 | then based on how big your cluster is ( maybe with 10 racks and 20 swithces) .. everyone sees this .. and then .10 will reply wtih i am at this mac | 16:45 |
ygk_12345 | ok | 16:45 |
admin0 | so if you say ping .20 ( an ip not used) .. you still see who has .20 .. reply to .1 arp request from the router, but since no one has .20 , you do not see the reply | 16:46 |
admin0 | sometimes its possible you are using a /18 ip range and you have 10 racks with 20 switches all in the same vlan .. all will get that arp request in the vlan | 16:46 |
admin0 | so think this as something between the router and your instance .. the switch only plays a dumb role of making that communication possible | 16:47 |
admin0 | the switch itself does not take part in the discovery process | 16:47 |
admin0 | but when that arp is done and all know where everyone else is, then the switch will redirect that communication to that particular port only where it knows that mac can be reached | 16:47 |

haleyb | zigo: so i just had one question on that review, in https://review.opendev.org/c/openstack/neutron/+/669395/29..31/neutron/db/ipam_backend_mixin.py my question on subnet.id | 20:26 |
*** zzzeek has joined #openstack-neutron | 20:27 | |
zigo | haleyb: TBH, I can't remember why I wrote things this way, but I vaguely remember it was needed, I'm currently re-reading the code ... | 20:29 |
*** tmorin has quit IRC | 20:30 | |
haleyb | zigo: ack, the code right above that is creating the subnet, so the passed ID probably is None, or that .get() at least returns None | 20:30 |
zigo | haleyb: That's what I remember (ie: that the subnet_id could be None), but I'm re-reading anyway. | 20:31 |

zigo | haleyb: The method _save_subnet is called with subnet_args and subnet_request, I don't see an object "subnet" as parameter to that method, so from where would the "subnet" object come from in such context? | 20:35 |
*** nweinber_ has joined #openstack-neutron | 20:36 | |
zigo | haleyb: Just below what I wrote, there is: | 20:37 |
zigo | segment_id = subnet_args.get('segment_id') | 20:37 |
zigo | so I just did the same and extracted the subnet_id from subnet_args.get('id') as it was there... | 20:37 |
haleyb | zigo: it's created on L596 and used on L613 | 20:37 |
zigo | Oh, makes sense now ... :P | 20:38 |
zigo | Ok, I'll do as you suggest then. | 20:38 |
haleyb | zigo: i'm assuming it's right, i guess i didn't know what subnet_id would be otherwise as the subnet didn't exist, would it always be None? | 20:39 |
*** nweinber has quit IRC | 20:39 | |
zigo | Oh, and the same thing (ie: subnet.id) is used just below when doing subnet_obj.DNSNameServer()... | 20:39 |
haleyb | right, so on L585 is it always None as it's the passed-in arg - is it there? | 20:40 |
