 Modular Layer 2 (ml2) Arista Mechanism configuration options

Table 9.18. Description of ML2 Arista mechanism driver configuration options
Configuration option = Default value Description
[ml2_arista]
eapi_host = (StrOpt) Arista EOS IP address. This is required field. If not set, all communications to Arista EOS will fail.
eapi_password = (StrOpt) Password for Arista EOS. This is required field. If not set, all communications to Arista EOS will fail.
eapi_username = (StrOpt) Username for Arista EOS. This is required field. If not set, all communications to Arista EOS will fail.
region_name = RegionOne (StrOpt) Defines Region Name that is assigned to this OpenStack Controller. This is useful when multiple OpenStack/Neutron controllers are managing the same Arista HW clusters. Note that this name must match with the region name registered (or known) to keystone service. Authentication with Keysotne is performed by EOS. This is optional. If not set, a value of "RegionOne" is assumed.
sync_interval = 180 (IntOpt) Sync interval in seconds between Neutron plugin and EOS. This interval defines how often the synchronization is performed. This is an optional field. If not set, a value of 180 seconds is assumed.
use_fqdn = True (BoolOpt) Defines if hostnames are sent to Arista EOS as FQDNs ("node1.domain.com") or as short names ("node1"). This is optional. If not set, a value of "True" is assumed.

Table 9.19. Description of Arista layer-3 service plug-in configuration options
Configuration option = Default value Description
[l3_arista]
l3_sync_interval = 180 (IntOpt) Sync interval in seconds between L3 Service plugin and EOS. This interval defines how often the synchronization is performed. This is an optional field. If not set, a value of 180 seconds is assumed
mlag_config = False (BoolOpt) This flag is used indicate if Arista Switches are configured in MLAG mode. If yes, all L3 config is pushed to both the switches automatically. If this flag is set to True, ensure to specify IP addresses of both switches. This is optional. If not set, a value of "False" is assumed.
primary_l3_host = (StrOpt) Arista EOS IP address. This is required field. If not set, all communications to Arista EOS will fail
primary_l3_host_password = (StrOpt) Password for Arista EOS. This is required field. If not set, all communications to Arista EOS will fail
primary_l3_host_username = (StrOpt) Username for Arista EOS. This is required field. If not set, all communications to Arista EOS will fail
secondary_l3_host = (StrOpt) Arista EOS IP address for second Switch MLAGed with the first one. This an optional field, however, if mlag_config flag is set, then this is required. If not set, all communications to Arista EOS will fail
use_vrf = False (BoolOpt) A "True" value for this flag indicates to create a router in VRF. If not set, all routers are created in default VRF. This is optional. If not set, a value of "False" is assumed.
