Steps to set up end-to-end/partial-path circuits Step1: End host requests the setup of a CHEETAH circuit between two routers with GMPLS signaling Done by end-host RSVP-TE software, VLSR for routers, and GMPLS engine on Sycamore SN16000 Step2: Configure the IP routing tables in routers to direct packets from the particular flow for which the circuit was requested to the circuit Done by VLSR for routers Step3: Configure the IP routing tables in hosts to direct packets from the particular flow to the CHEETAH router, instead of the default Internet router Done by end-host RSVP-TE software

Local demo Step1: Set up the circuit between two routers Done by manually provisioning the circuit on 15454 MSPP Step2: Configure the IP routing tables in routers to direct the traffic destined to mvstu4 and mvstu5 via two 15454 paths Done using CLI commands in the routers Step3: Configure the IP routing tables in hosts to direct the right traffic to router A and B, instead of the default Internet router Done using Linux “route” command in the hosts Step4: Run “traceroute” on mvstu3 to demo the different paths taken for different flows
