961 | call WORD - If this clause is matched, then the set statements | |
962 | are executed and then we jump to route-map 'WORD'. If | |
963 | this route-map denies the route, we finish, in other case we | |
964 | do whatever the exit policy (EXIT, NEXT or GOTO) tells. | |
3bf1c917 | 965 | on-match next - If this clause is matched, then the set statements |
966 | are executed and then we drop through to the next clause | |
967 | on-match goto n - If this clause is matched, then the set statments | |
968 | are executed and then we goto the nth clause, or the | |
969 | first clause greater than this. In order to ensure | |
970 | route-maps *always* exit, you cannot jump backwards. | |
971 | Sorry ;) | |
