Inconsistent VRF Names on Cisco Platforms

For different Cisco families, the default VRF name may be inconsistent in technology tables where the VRF name is present. There are the following examples:

  • Cisco IOS – using default string to identify main VRF
  • Cisco IOS-XE – using empty string to identify main VRF

As per the following example, the excerpt from the Technology → Addressing → Managed IP table, all records are for Cisco devices, but different families are involved:

Inconsistent VRF names

How the Internal Algorithms Operate

Internally, IP Fabric understands the discrepancy and uses the special labels to identify default VRF and to simulate the end-to-end path correctly.
