yes, but only if you had the available subnets in the 192.168.113.x,
192.168.114.x , and 192.168.115.x range. (You can't use the subnets that
are already defined by OSPF) What you really want is to have are those
particular routes with the proper masks advertised throughout the IGRP
network. Thus, if the subnets were indeed available... you could on the
IGRP router define
ip subnet-zero
interface loopback1
ip address 192.168.113.1 255.255.255.192
interface loopback2
ip address 192.168.114.1 255.255.255.128
interface loopback3
ip address 192.168.115.1 255.255.255.240
router ospf 1
<yada yada yada>
router igrp 1
redistribute ospf 1 metric <metrics metrics metrics>
network 192.168.113.0
network 192.168.114.0
network 192.168.115.0
which would then define the fixed mask length for those networks in the IGRP
AS, same as the static routes would do.
