Issue with HUB n SPOKE MPLS

[Olugbenga.Abiodun]

Hi All,

          I am working with an MPLS VPN in a Hub and Spoke fashion but hindered by a configuration on the HUB PE.

All the configuration at the three sites are well understood, with the exception of a config on the HUB PE, which configures a vrf without a RD.

I tried the same but the PE refused accepting the " route-target" without a RD. Can anyone please help out?.

Thanking you all in advance,

Hi,

You need to configure an RD, also on the hub router, for MPLS VPN. Why would you not configure an RD?

With hub-and-spoke, you need to be mindful of how to import and export the RTs, but the RDs need to be there.

Just configure an unique RD per spoke/hub PE router. Have a RT for spoke-to-hub and RT for hub-to-spoke.

You can also look at a specific solution (half-duplex VRF) here:
