Hope you have TONS of fun with this blog series!

I needed to build a full MPLS cloud with L3VPN unicast and multicast for a CPOC.  🙂   Figured what the heck… bring y’all along for a “knowledge sharing ride-along”.

Ultimately what I want to do is have a multicast source up in Headquarters (upper left) and multicast receivers down in Site11 and Site 12 joining those groups.

For this blog series that will mean

• 6 blogs,
• zip files of the varying configs as we build them,
• plus sniffer traces for you to download and refer to.

MPLS Fun in the Lab: Building the MPLS Cloud – Part 1 of 6

Create the MPLS cloud and prep it for MPLS L3VPN Unicast for One L3VPN Customer

• OSPF area 0
• MPLS LDP neighbors between the PEs and the P
• BGP VPNv4 peers from all PEs to the VPNv4 Route Reflector

MPLS Fun in the Lab: Connect a Customer – Part 2 of 6

• Create a VRF in each PE.
• Apply the VRF and IP addresses on the interfaces in each PE towards the CEs.
• Create the BGP neighbors in the PEs towards the CEs.
• Ping from HQ to Site 11
• Look at the sniffer trace of the above Ping

MPLS Fun in the Lab: Following the Labels – Part 3 of 6

Put your Network Detective badge on and follow along as we look at labels from a sniffer trace and try to reverse engineer where in the network the capture was taken.  🙂

MPLS Fun in the Lab: Add the Multicast at the Customer – Part 4 of 6

• Enable Multicast-Routing globally
• Enable PIM on all relevant interfaces
• Configure both with the same Rendezvous Point

MPLS Fun in the Lab: Add the Multicast in the Cloud – Part 5 of 6

• Multicast-Routing/PIM enabled in the Core to Pass the Multicast
• BGP IPv4 MDT for the Rosen Draft MVPN

MPLS Fun in the Lab: Troubleshooting the MVPN Cloud – Part 6 of 6

I always learn better when I need to troubleshoot something.  So toss your Network Detective hat on and join me for a Troubleshooting mVPN ride-a-long
