Terraform IOS-XE EVPN OSPF Underlay Module
This module can manage a Catalyst 9000 EVPN fabric underlay network based on OSPF.
The following assumptions have been made:
- IP unnumbered is used on all fabric links
- OSPF area 0 is used for all interfaces
- PIM sparse mode is enabled on all interfaces
- A system MTU of 9198 is configured on all devices
- All spines act as a PIM RP (Anycast with MSDP)
- Each leaf is connected to each spine with a single link
- The same consecutive range of interfaces is used on all leafs for fabric links
- The same consecutive range of interfaces is used on all spines for fabric links
