OSPFv2 Auto-peering

ExtremeXOS 30.6 introduces OSPFv2 auto-peering, which is a network of cooperating interconnected devices that automatically create an OSPFv2 network for any topology, providing fully redundant, multipath routing. Node participation grows dynamically and is not bound to any well known topology such as Clos or Leaf/Spine. OSPF is a link-state routing protocol providing fast convergence and scalability.

Note

Note

BGP and OSPFv2 Auto-peering are mutually exclusive. Only one form of Auto-peering can exist at a time.

Supported Platforms

ExtremeSwitching X590, X465, X670-G2, X690, X695, and X870 series switches.

Limitations

The following capabilities are not supported on OSPFv2 Auto-peering:
  • Stacking
  • Automatic LAG configuration with MLAG
  • Automatic LAG configuration with Extended Edge Switching
  • Static Lag attachments to AutoOSPF
  • AutoOSPF links on Extended Edge Switching ports
  • MPLS, VPLS, L2VPN, L3VPN
  • PIM snooping, PIM-SM, PIM-DM, SSM mode
  • OSPFv2, OSPFv3, ISIS, RIP, RIPNG per VRF
  • Automatic MLAG configuration
  • Multiple links between two OSPFv2 auto-peering enabled switches (instead LAG can be configured to avoid connectivity problem due to link failure).
Other limitations:
  • One MLAG peer per node.
  • Static router must be an external router per VRF.
  • VLANs spanning multiple bridges, where each bridge is automatic configured LAG-connected, must be VXLAN-based or replaced with MLAG.

New CLI Commands

create auto-peering ospf routerid ipaddress

Changed CLI Commands

Changes are underlined.

The following command now deletes OSPFv2 Auto-peering, as well as BGP Auto-peering:
