Hi all, I have two DCs that work as multi-site , IE all subnets are available in both DCs. Using spine/leaf setup, two spines (QFX10000) on each site. Using the Central GW setup, the spines are L3 GWs. In the overlay BGP a filter has been included so the leafs see only their own site spines, and will result in the traffic always using the nearest spine to reach the WAN. A design problem I have found now is if the return traffic to a leaf in site1 comes via site2 spines. The spine in site2 will add a vxlan header and send it leaf in site1, but the leaf will drop the traffic as the spine is unknown (as I have designed the solution).
I need suggestions on how to solve this. A very easy way is to remove the filter so all leafs see all spine, but the drawback will be that a leaf in site1 can use a spine in site2 as L3 GW. Cisco has a solution called "VXLAN EVPN Multi-Site Design", I have not seen any simulare example for juniper.
