Topology used is over here: http://mellowd.co.uk/ccie/?p=243

BGP Lab 8:

  • Address as normal in the topology – Add the loopback of 99.99.99.99 and 22.22.22.22 to Router’s 9 and 2 respectively
  • All routers are peered via BGP with OSPF running as well
  • Use a filter on AS500 to ensure it is non-transit
  • Company1 now wants to prepend it’s AS number 3 times for any route sent off to Customer2
  • Allow Customer3 to transit through ISP1
  • Ensure Customer3’s Private-AS number is stripped off before advertising it out
  • Allow Company1 and Company2 to get to Customer3
