Clos Fabric with Auto VNI Map
- In Clos fabric with auto VNI map,
the VNI is statically derived using the VLAN ID or BD ID.
- For the VLAN case, VNI = VLAN ID
- For the BD case, VNI = 4096 + BD ID
- You cannot reserve l2-vni-range or l3-vni-range for a given tenant.
- You cannot provide a specific l2-vni or l3-vni in an endpoint group.
- VLAN Based Tenants:
Multiple VLAN based tenants cannot share the same VLAN, considering the multiple tenants cannot share the same VNI.
- BD Based Tenants:
Multiple BD based tenants can share the same VLAN, as the VLANs from each tenant are mapped to a unique BD and further a unique VNI.
Multi Tenancy
EFA supports multi tenancy by allowing multiple tenants to have overlapping ctags and non-overlapping L2VNI. A tenant ctag will get a unique L2VNI and a unique network allocated in the fabric
The following example shows a multi tenancy configuration.
efa tenant create --name tenant11 --vrf-count 10 --vlan-range 2-4090 --port 10.24.80.134[0/15-17],10.24.80.135[0/15-17],10.25.225.11[0/15-17],10.25.225.46[0/15-17],10.24.85.74[0/15-17],10.24.85.76[0/15-17] --description Subscriber1
