This week I've been busy preparing course content for a VoIP and IMS two day overview, trying to get my Cisco Lab into shape for demonstrating MPLS-TE, MPLS VPNs and routing using OSPF and BGP.
I've also got a Vyatta router talking OSPF to the Cisco stack, and now need to get the OSPF running against my Netgear FSM7328S switch. With the aim of running my IP-phones over one MPLS LSP whilst other traffic goes over a separate LSP.
Why go to all this trouble in a lab setup? I believe the only way to confidently teach a topic is to understand practically how it works.
