969 | call WORD - If this clause is matched, then the set statements | |

971 | this route-map denies the route, we finish, in other case we | |
972 | do whatever the exit policy (EXIT, NEXT or GOTO) tells. | |
3bf1c917 | 973 | on-match next - If this clause is matched, then the set statements |
974 | are executed and then we drop through to the next clause | |
975 | on-match goto n - If this clause is matched, then the set statments | |
976 | are executed and then we goto the nth clause, or the | |
977 | first clause greater than this. In order to ensure | |
978 | route-maps *always* exit, you cannot jump backwards. | |
