OSPFv2 in NX-OS

When you configure a summary address, Cisco NX-OS automatically configures a discard route for the summary address to prevent routing black holes and route loops.

OSPFv2 has the following configuration guidelines and limitations:

  • You can have up to four instances of OSPFv2 in a VDC.
  • Cisco NX-OS displays areas in dotted decimal notation regardless of whether you enter the area in decimal or dotted decimal notation.
  • All OSPFv2 routers must operate in the same RFC compatibility mode. OSPFv2 for Cisco NX-OS complies with RFC 2328. Use the rfc1583compatibility command in router configuration mode if your network includes routers that support only RFC 1583.
  • You must configure RFC 1583 compatibility on any VRF that connects to routers running only RFC1583 compatible OSPF.
Reference bandwidth for link cost calculation 40 Gb/s
