MPLS VPN – routes sharing between 2 different VRFs across the MPLS network

Leave a reply

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

MPLS – check the label switching path with Juniper Junos and Cisco IOS

Leave a reply

How yall doing guys. It has been some times putting anything new to my blog. I think I will put some more materials that focus on troubleshooting wise stuffs. This time, I will present the way to check the label switching path or routing path of the MPLS VPN traffic that run on top of the OSPF and LDP protocols.
Here is the Topology. The lab is build with both Cisco IOS (C1000v) and JunOS. There is 2 subnets in the VRF which are 192.168.104.0/24 and 192.168.109.0/24 and they are located in the R3 and R10 respectively.
