4 Configuring the NCL1170
APCD–NC006–A 21
The NCL1170 supports both RIP versions 1 and 2. You can set RIP version 2 to either
broadcast, compatible, or multicast modes.
CAUTION: RIP version 1 exchanges the minimal amount of information
necessary for an NCL1170 to route packets through a network, and does not
consider subnetting, which is required to determine the best route. If the designated
RIP route is a network route, RIP version 1 will interpret the network mask and
subnet mask as the same, which may not always be correct. To avoid possible problems, we
recommend NCL1170 users install RIP version 2, which exhanges explicit subnet and ‘next-
hop’ information for each route.
1. At the NCL1170> prompt, type <ip rip enable> to enable RIP as the routing
mode.
2. To transmit the route information in packets, type <ip rip active>.IfRIPissetto
quiet, it receives and processes RIP packets, but it does not transmit them.
3. Type <ip rip version> to display the current version of RIP.
4. If RIP is version 1, it is broadcast only. To change RIP routing to support version 2,
type <ip rip version 2>.
5. If you set RIP to version 2, you can additionally specify how RIP handles packets.
6. To enable RIP to advertise the default route, if one exists, in the advertisement, type
<ip rip default>.
To set RIP to advertise static routes, as well as all other RIP information, type
<ip rip update>. To send all route information except static route data, type <ip
rip noupdate>.
To do this.... Type...
Disable RIP Routing <ip rip disable>
Enable RIP routing. <ip rip enable>
Send version 2 advertisements as broadcast. <ip rip broadcast>
Send version 2 advertisements to RIP version 2
multicast addresses. This is generally more efficient
than broadcast.
<ip rip multicast>
