The beaut of MPLS VPN is to have multi tenants running over the same MPLS core network and each tenant are prevented to access other tenants networks. But what if the 2 different tenants want to connect to each other?
In the lab below, we have 2 different tenants and they are 1120020010 (RT:200010) in Router 12 and 1030010010 (RT:100010) in Router 03. By default, the ASAs connected to these VRFs cannot communicate since they are in 2 different VRF network. In this case, I will be using Cisco IOS and Juniper MX to let 2 different VRFs to connect together.
We could check the existing configuration and the route table in Router 03 and Router 12
