Internet Protocol (IP) Routing
routes from all nodes on a particular interface. In either case, be sure to set the proper subnet masks
for the subnet addresses on the network. Also, be aware that RIP 1 packets do not have fields
containing subnet masks. Thus, both ends of a RIP 1 communications link must agree beforehand
on the part of an address that contains the subnet specification.
Figure A12-6 shows an example in which host03 learns routes to the PC at 132.254.93.2 and the
host at 132.254.55.222, even though they are on different subnets from that of the Model 5390
server. This is because
(1) the Model 5390 server has the rip_sub_advertise parameter set to Y, and (2) all nodes have a
subnet mask set (correctly) to 255.255.255.0.
Figure A12-6. Advertising Subnet Routes
Subnets are explained in Subnetting Using Subnet Masks on page A12-13. The rip_sub_advertise
parameter is described in more detail on page A-61.
NOTE:
For convenience, the local addresses of the links to the PC
and host14 in Figure A12-6 are configured to be the same as the
Model 5390 server’s en0 interface – 132.254.66.134. If host03 supports
host routes, a subnet mask of all 1s (255.255.255.255) would work for
the two serial ports on 5390_01.
