summary-address 172.17.0.0/24 will work too. This
command on router A OSPF process only works when this
ospf router is a ASBR. which means if there is no
"redistribute xxx" command under ospf process, this
command does not work. This command will add an ospf
summary route point to null0 on router A. and this
route can be redistributed to igrp with the command
redistribute ospf under igrp process.
IGRP does not use 0.0.0.0 as the default route. The
default-information in/out command under igrp process
permit or deny the default route generated by "ip
default-network" command.
