IOS commands to do dynamic routing.

From global config mode:

router rip           (go into (RIP) routing config mode)

  network NET          (a network this routing process is responsible for,
                      i.e. will advertise to other routers its route
                      to this network.
                      RIP is classful, so netmask is implied by class.
  redistribute static  include static routes in advertisements.

  passive-interface INT   do not advertise out this interface

  maximum-paths N         max equal-metric routes. default is 4


show ip route     to see changes in routing table.
sh ip protocols   to see status of routing protocols
debug ip rip      to see send/recv of RIP advertisements
debug ip routing  to see changes to routing table


router igrp ASN             #Obsolete 
 variance MULTIPLIER


router ospf PID                 #PID can be anything but use same on all routers for documentation

                                #advertize nets of that IP interface
