The confusion in this … Continue reading MPLS – Finishing up Redistribution / Connectivity between Customers over the MPLS / L3 VPN, a review of everything learnt up to this point, and all running configs published for future review!
This will be sort of the beginning of the end of the this MPLS series I am going through, Layer 3 VPN is really the last piece of "Cisco Magic" happening on the Provider Edge routers at work, segregating customer traffic on the same device using VRF instances along with MBGP to forwarding them across … Continue reading MPLS – Layer 3 overview, mBGP Configuration, and VRF Configuration reviewed (and how it all works together!)
Will be doing a very simple IGP setup using OSPFv2, MPLS, and doing some verification commands to demonstrate different ways to verify MPLS Bindings / LDP in action / Labels through the LSP (Label Switched Path). However first upon booting up my lab I saw my Layer 3 VPN tunnel throw a console message, so … Continue reading MPLS – Layer 3 VPN configuration review on PE Routers, configuration of Provider Routers, and verification commands!
