What to Do Next
Verify that the correct virtual network identifier (VNI) is being used.
Verify That the Correct VNI Is Used
You can verify that the correct virtual network identifier (VNI) is being used.
Because of a limitation with a Cisco Nexus 7000 Series spine switch that is running in transit mode, the
segment-ID and VNI range that you can use on the leafs/border leafs are determined by the VLAN configured
on the spine switch.
segment-ID and VNI range that you can use on the leafs/border leafs are determined by the VLAN configured
on the spine switch.
Before You Begin
• Verify that the unicast connectivity is established.
• Verify that the Border Gateway Protocol (BGP) sessions are established.
Step 1
Determine which VLANs are configured on the Cisco Nexus 7000 Series spines. In the following example, VLAN 1 is
configured on the spine route reflector (RR).
