route-map cogent-ick permit 10
match community-list <aggregate-only>
set as-path prepend <iamuglypath> <iamuglypath> <iamuglypath>
route-map cogent-ick deny 20
match community-list <deaggregated-routes>
route-map happy-with-backup permit 10
match community-list <deaggregated-routes>
route-map happy-with-backup deny 20
match community-list <aggregate-only>
