CLI Commands B-27
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 required parameter for this 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 networks
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 supported 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 standard 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 network 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 it
received a particular route and does not propagate its information 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 infinite 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 split 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.
<interface_name> Designation of interface you are setting parameters for. Limit of 32
characters.
filter_access ON causes filters specified for an interface with a set interface command,
to override filters specified with a set user command, when the filters are
of the same type.
input_filter Name of filter file you wish to be applied to the input stream coming in on
the specified interface. Limit: 20 characters.
output_filter Name of the filter file you wish to be applied to the output stream leaving
the specified interface. Limit: 20 characters.
