ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER REFERENCE MANUAL

host_addr—Enter the address of the host to add to the RIP table.

seconds—Enter the number of seconds of the intervals when the RIP table is updated with this address.

flags—If set to 1, then split horizon processing is performed for the destination. That is, any IP routing table entries pointing to the interface to be used to send this update will be removed from the update. If split horizon processing is not specified, then all routing table entries except those marked private will be sent at each update.

rip delete host_addr

Remove an entry from the RIP table for the host with address host_addr. This is the opposite of the rip add subcommand.

host_addr—Enter the address of the host to delete from the RIP table.

rip duplicate [{on off}]

Allow multiple routes to the same destination to co-exist in the IP routing table.

off—Only one route will be retained for any remote destination. This is the normal IP RIP behavior, and the default in the Router.

on—Multiple routes to the same destination may be retained in the IP routing table. This is required for automatic fallback (from a leased sync line to a dialup async modem connection), and will be automatically set up when such a configuration is created with the config command. The rip duplicate on command also automatically sets rip merge off.

rip merge [{on off}]

Enable or disable merging of RIP table entries.

on—Enable merging RIP table entries. When enabled, the table is scanned after processing each RIP update packet. If an entry is redundant, it is deleted from the table. An entry is considered redundant if the target(s) it pertains to is routed identically by a less specific entry already in the table. The target address(es) specified by the entry in question must also match the target addresses of the less specific entry, and the two entries must have the same interface and router fields.

off—Disable merging RIP table entries.

rip netmask add net_addr /net_bits /subnet_bits

Inform RIP of the netmask to be applied to addresses in incoming routing information packets, to create the correct routing table entries for networks that do not have 16 bit or 24 bit netmasks. For instance, the command

rip netmask add 128.66.0.0/16/20

informs RIP that within the class B network 128.66.0.0, 20-bit subnets are used (i.e. the netmask is 255.255.240.0). In order to describe an area with smaller subnets within this network, you could add the command

rip netmask add 128.66.192.0/20/24

If you create networks where different subnets use different masks, be aware that different RIP implementations may not be compatible with your network after this is done.
