RIP Control
Use this section to configure the RIP control settings. RIP is used by some cable operators to
advertise Public LAN IPs to their network. Below is an outline of the RIP control options:
1. RIP Send Version:
Options are to send RIP1| RIP2| RIP1 and RIP2| DO NOT SEND.
2. RIP Receive Version:
Options are to receive RIP1| RIP2| RIP1 and RIP2| DO NOT RECEIVE.
3. Update Interval:
Time period for RIP daemon to send out its routing information to other routers.
4. Default Metric:
This variable indicates the metric that is to be used for the default route entry in RIP
updates originated on this interface. A value of zero indicates that no default route
should be originated. For CM, it is not necessary to send out its own default route to
the CMTS. So, this value should be zero.
5. Authentication Type (only for RIPv2):
This value is used when users choose RIP2 for the RIP SEND/RECEIVE. The options are
No authentication| Simple Password| MD5. The Simple Password option uses a clear
text password. Usually, MD5 is preferred for security reason. Please be aware that the
CMTS's RIP setting must match with the CM's RIP setting.
6. Authentication Key & ID (only for RIPv2):
These two values are used with item 5 above. If “Simple Password” or “MD5” is chosen
for authentication type, they must match the values set in the CMTS.
7. Neighbor: Usually RIP are sent out by broadcast or multicast. If users want to unicast
the RIP to a specific neighbor router, they can specify the destination IP here. Then
only that particular neighbor router would receive the RIP messages.
NOTE: It is best to use RIP2 when using non-classful IP addresses. In other words, use RIP2 for
those networks that are subneted (e.g. a subnet mask other than 255.0.0.0 for a Class A IP
address). RIP1 does not support classless inter-domain routing (CIDR) which is the method used
to subdivide networks with subnet masks.
