Gslb to nexus 9k connection

[swati-srivastava999]

Can we connect 2 GSLB pair to single 9k leaf switch ?

Both GSLB pair are using vlan HA vlan 100 and having different snip vlans.

HA vlan 100 is L2 vlan used for heartbeat and HA .

HA vlan on gslb side is untagged and used as native vlan.

will there be any conflict wrt to HA vlan on 9k leaf switch ? on 9k leaf switch mac address should be learned from vlan 100 or 900?

As per the Switch concern VLAN 100 will be one broadcast domain, how the GSLB will act based on the configuration.

Switch always learn the MAC address on respect VLAN, not from Native VLAN.

If all GSLB need to in the VLAN 100, then your setup looks ok as per my views.

Both leaf run vPC? If yes why only vlan50 is allow in trunk between leafs

Hello @swati-srivastava999 

Instead of using VLAN id 100 for both GSLB pairs, allocate separate vlan for HA traffic (=> VLAN 100 for one GSLB pair and VLAN 101 for the other). This should prevent MAC learning issues and ensures proper HA synchronization...
