How can we communicate from traditional network setup to Service VPN of Viptela?

Hi, I'm building a LAB and would like to know if what option should I use to communicate from Viptela Service VPN to Traditional network connected to MPLS. Refer to the topology.

Topology: https://ibb.co/p4nkxDb

I did try redistributing OMP route to VPN 0 however it is not allowed.

Aborted: 'vpn 0 router bgp 300 address-family ipv4-unicast redistribute omp' : configuring redistribute omp is not allowed in vpn 0

What is the usual approach on this? Do we really need to install a vEdge at the site?

I'm also checking other solution but if you can share some of the options that being used in production.

Thank you
