Peered Spokes Routes to HUB Vnets are not advertised in the Hub ExpressRoute Route table

Hello,

We have linked an ExpressRoute circuit to our Hub & Spoke topology via a virtual network gateway on our Hub Vnet.

The problem is we can only see the On-premise and HUB Vnet Routes in the Circuit Route table and not the Spokes Routes.

What can we do to advertise spokes routes into the circuits ?

Please we need some help.

Best regards

    @BENCHEIKH Louey , Please do check whether the remote gateway transit is enabled between Hub and Spoke peering network. This might be the major cause why ExpressRoute is not able to learn spoke routes.

    Configure VPN gateway transit for VNET peering.
