MPLS – A necessary closer look at the PE Router settings (VRF / BGP / VPN / Address Family) to see how to setup for new lab!

I have a confession to make - While studying MPLS I largely overlooked the configuration of the Provider Edge because of its complexity and ease of breaking all routing (and probably reversing time). I intentionally used my MPLS Lab for ENARSI 300-410 study with new IP Schemes / CE Protocols to challenge my knowledge of … Continue reading MPLS – A necessary closer look at the PE Router settings (VRF / BGP / VPN / Address Family) to see how to setup for new lab!

GET VPN – Key Servers, Group Members, and Tunnel-less VPN Tunnels some how!

GET VPN or Group Encrypted Transport VPN is a whole different animal than Tunneling traffic between sites in an integral / encrypted manner, as it is a "Tunnel-less" approach to VPN between Branch locations! Some important components to GET VPN that make it possible KS / Key Server = Responsible for pushing "GET VPN" Policy … Continue reading GET VPN – Key Servers, Group Members, and Tunnel-less VPN Tunnels some how!

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!

After taking a step from this lab to think about what is logically needed to make this work, I realized there is no "Redistribution" propagating routes over the L3 VPN between Customer A Site 1 / Customer A Site 2, so they have no idea how to respond to each other. 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!

MPLS – Layer 3 overview, mBGP Configuration, and VRF Configuration reviewed (and how it all works together!)

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!)

MPLS – Layer 3 VPN configuration review on PE Routers, configuration of Provider Routers, and verification commands!

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!
