1941 routing algorithms and their modifications can be found in~\cite{RFC1812}.
1946 This task is called ``policy routing''.
1949 ``policy routing'' $\neq$ ``routing policy''.
1951 \noindent ``policy routing'' $=$ ``cunning routing''.
1953 \noindent ``routing policy'' $=$ ``routing tactics'' or ``routing plan''.
1956 To solve this task, the conventional destination based routing table, ordered
1957 according to the longest match rule, is replaced with a ``routing policy
