I'm trying to understand a config.
This is a Hub and Spoke VPN over MPLS.
There is a PE with a VRF configured as the Hub.
There are other PEs with several VRFs acting as the Spokes.
Everything looks clear to me except for a detail, in the PEs where the spokes are configured there is a kind of major VRF also configured... this VRF inport and export the same than the rest of the spoke VRFs... so... I would like to know the reason of configuring that VRF, I thought that It was enough just with the spokes.
Thanks a lot in addvance,
