This module can manage a Catalyst 9000 EVPN fabric overlay.
The following assumptions have been made:
- A working underlay network including VTEP loopbacks is pre-configured (e.g., using the EVPN OSPF Underlay Terraform Module)
- A single BGP AS is used for all devices with spines acting as route reflectors
- All services will be provisioned on all leafs
- No L2 or L3 access interfaces will be provisioned
- A
l2_servicerefers to a single L2 VNI - A
l3_servicerefers to a single VRF and L3 VNI - A
l3_serviceSVI will be provisioned as an anycast gateway on all leafs with a corresponding L2 VNI - If no
ipv4_multicast_groupis configured ingress replication will be used
