B-26 APPENDIX B: CLI COMMAND DESCRIPTION
set ip network <name> broadcast_algorithm [number]
reassembly_maximum_size [number]
rip_authentication [string]
rip_policies_update <rip_policies>
routing_protocol [NONE | RIPV1 | RIPV2]
Sets the broadcast algorithm, the maximum size used for reassembling
fragmenting packets, the RIP authentication string, RIP policies, and the routing
protocol for the specified interface. The only requir ed param eter for th is command
is <name>. All other parameters are optional. You can set all of them at once, or
one at a time. This command can only be used on IP networks that have already
been defined using add ip network. You can list the currently defined IP ne tworks
using list ip networks. You must also disable the network before setting these
parameters, using disable ip network.
RIP Policies : The following RIP policies are supporte d by the IP route:
Send Default - disabled by default, causes router to advertise itself as the
default router.
Send Routes - enabled by default. Tells RIP to advertise (broadcast) its routes
on the network every 30 seconds - is standa rd for a gateway router.
Send Subnets - disabled by default. If this flag is on, only routes having the
same network mask and are subnets of the same netw ork are sent out the
interface.
Accept Default - disabled by default. Determines whether router accepts
default route advertisements.
Split Horizon - enabled by default. Records the interface over which i t
received a particular route and does not propagate its info rmation about that
route back over the same interface. This prevents route broadcasts from
looping between routers.
Poison Reverse - enabled by default. Routes that were excluded due to the
use of split horizon are instead included with infinite cost (16). The system
continues to broadcast the route, but with an infini te cost. This policy speeds
the news that a link is down to the rest of the internetwork’s routers. In
general, it performs better when used with spl it horizon.
Flash Update - enabled by default. It is also known as “triggered update”,
meaning broken routes will be advertised immediately, instead of waiting for
the next scheduled broadcast.
The following flags are for backward compatibility with RIP version 1 when RIP
version 2 is selected as the routing protocol:
Send Compatibility - Controls the selection of destination MAC and IP
addresses. It is enabled by default. When enabled, broadcast address is used;
when disabled, multicast address is used.
RIP V1 Receive - Controls the receipt of RIP version 1 updates. When RIP
version 1 is the selected routing protocol, this policy is enabled by default,
which means RIP version 1 packets are rece ived. (When RIP version 2 is chosen,
this policy is enabled by default, meaning RIP version 1 packets are received.
