Hyperflex Replication Network Configuration

Folks,

I'm trying to configure Hyperflex replication network pair between cluster 

replication network will be using different vlan on each cluster

let say site A using vlan 248 and site B using vlan 249 (both routable between cluster)

since replication vlan already add to UCSM and ESXI I chose existing vlan

but when adding IP range, error appear "Pre Replication Network Configuration validation failed. IP address: 10.1.248.14 is already in use. Please verify there are no duplicate IPs"

no matter which IP range used it always say the fourth IP is duplicate

for example If I start with 10.1.248.100 it will say 10.1.248.103 is duplicate

replication vlan is newly created and I can assure no device using the fourth IP 

I really appreciate any insight regarding this issue

 

Thanks 

Budi

First, each cluster is set up for replication networking. Use HX Connect to provide a set of IP addresses to be used by local cluster nodes to replicate to the remote cluster. HX Connect creates VLANs through UCS Manager, for dedicated replication network use.
