Route Map Examples
The examples in this section illustrate the use of redistribution, with and without route maps. Examples
from both the IP and Connectionless Network Service (CLNS) routing protocols are given.
The following example redistributes all OSPF routes into IGRP:
router igrp 109
redistribute ospf 110
