Configuring VXLAN BGP EVPN
• In VXLAN vPC deployments with F3 modules, the vPC peer-link should be on an isolated ASIC instance
from the Layer 3 core ports. After changing the peer-link ports to an isolated ASIC instance, ensure that
you reload the switch.
• In a VXLAN vPC deployment with F3 modules and connected FEX devices, unknown unicast traffic from
a remote source to the vPC switch pair may result in duplicate traffic if the MAC address is known to
the vPC switches. Both vPC switches will receive a copy of the packet and forward it to the receiver
behind FEX.
• In a VXLAN vPC deployment with F3 modules, known unicast traffic from a remote source to the vPC
switch pair may result in loss of traffic if the MAC address is no longer known to the vPC switch pair.
• In a VXLAN vPC deployment with peer switch, encapsulation profile, and bridge domain configurations,
the vPC secondary peer switch does not generate or process BPDUs for bridge domains.
• If the vPC feature is enabled on a non-vPC (standalone) switch, the NVE source loopback will be in
shutdown state after an upgrade. To restore the interface to up state, remove the vPC feature using the
no feature vpc command in global configuration mode, as shown below.
switch(config)# no feature vpc
