One thought on “Which three configurations can be different between EVPN vPC peers?

  1. Answer: B for sure.
    Others – difficult to say.
    http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/vxlan/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_7x_chapter_0100.html

    VPC peers must have identical configurations.
    Consistent VLAN to VN-segment mapping.
    Consistent NVE1 binding to the same loopback interface
    Using the same secondary IP address.
    Using different primary IP addresses.
    Consistent VNI to group mapping.

    For VPC, the loopback interface has 2 IP addresses: the primary IP address and the secondary IP address.

    The primary IP address is unique and is used by Layer 3 protocols.

    The secondary IP address on loopback is necessary because the interface NVE uses it for the VTEP IP address. The secondary IP address must be same on both vPC peers.
