Exercise 4: Filtering peer routes using prefix-list

• Create “ip prefix-list my-routes” to match your own routes

• Create “ip prefix-list peer-as-xxx” to match your peer’s routes

• Apply the filters to your peers

  • “neighbor xxx prefix-list my-routes out”
  • “neighbor xxx prefix-list peer-as-xxx in”

• Apply the outbound filter to your upstream provider
