MPLS VPN – option C – using bgp label exchange with cisco and Junos -part 1

It has been a while since I have done any labs after getting a new job. This time, I will be building a NNI option C using both Cisco IOS and Juniper MX. The reason I write this is because I do not find many resources on the internet about the inter AS connection using 2 different software at the same time. Hope this can be useful for anyone who is having the same struggle as i do.

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

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.
