Public bug reported:
Hi,
I am trying to set up OVN using Openstack.
OS: CentOS Stream release 8
OVN 21.06
Openstack wallaby
When creating a network in openstack, we get an error:
"Segmentation ID should be lower or equal to 4095."
ml2 config:
# ML2 general
[ml2]
type_drivers = flat,vlan,vxlan,geneve
tenant_network_types = geneve
mechanism_drivers = ovn
extension_drivers = port_security,dns
physical_network_mtus = vlan:1500,floating:1500
path_mtu = 1558
overlay_ip_version = 4
# ML2 geneve networks
[ml2_type_geneve]
vni_ranges = 5000:6000
max_header_size = 38
# ML2 VLAN networks
[ml2_type_vlan]
network_vlan_ranges = vlan:3900:3999
# ML2 VXLAN networks
[ml2_type_vxlan]
vni_ranges = 5000:6000
# Security groups
[securitygroup]
enable_security_group = True
firewall_driver =
neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
[ovn]
ovn_nb_connection = tcp:<IP>:6641
ovn_sb_connection = tcp:<IP>:6642
ovn_l3_scheduler = leastloaded
ovn_metadata_enabled = True
isolated_metadata = True
When I execute the command
$ ovn-nbctl get NB_Global. options:max_tunid
or
$ ovn-sbctl get SB_Global. options:max_tunid
I get "4095"
If I manually try to change max_tunid using the command
$ ovn-nbctl set NB_Global. options:max_tunid="16777215"
or
$ ovn-sbctl set SB_Global. options:max_tunid="16777215"
then no change occurs.
How can I change max_tunid from 4095 to 16777215 for supporting geneve
or vxlan networks in Openstack.
