PAcket loss in VXLAN within L2 OUT VLAN: Border Leaves in Back-To-Back vPC to the CORE (VRRP Gateway)

Post by MSLAV » Tue May 14, 2019 10:16 pm

Hello all,

I'm facing a weird problem:

I have VXLAN EVPN BGP with Border Leaves (BL) configured as vPC.
BLs are Back-to-Back vPC to the CORE of the network, and CORE has a VRRP for VLAN 805.

VLAN 805 is a bridged VLAN and VXLAN VNI configured for it as well: PCs in this vlan are connected to Leaves and reaching its GW on the CORE.
CORE has SVI 805 with vrrp


The problem is that I'm losing packets when pinging GW or from PCs behind Leaves when VRRP master is CORE-NXOS-1 and I can not understand why.
WIll appreciate if someone can figure out

Thank you in advance
