routing updates. (See Chapter 9: Configuring a Tunnel with Generic Routing
Encapsulation.) A router that receives and accepts the redistributed route
adds it to its routing table as a RIP route.
By default, RIP interfaces advertise redistributed routes with a metric of zero,
as if they were directly connected. However, many redistributed routes may
be several hops away or even at a remote site. You can change the default
metric for all redistributed routes by entering this command from the RIP
configuration mode context:
Syntax: default-metric <value>
This command changes the metric only for redistributed routes. You cannot
alter the metric for RIP routes, which always equals the hop count.
You can override the default metric for different types of redistributed routes
by using the metric keyword in the redistribute command. From the RIP
configuration mode context, enter:
Syntax: redistribute [connected | ospf | static] [metric <value>]
For example, you can set a higher metric for OSPF routes but leave the metric
for redistributed connected routes at the default of zero. The following
sections will discuss the different types of route redistribution in more detail.

Redistributing Connected Routes

Certain network topologies and security policies might prohibit an interface
from transmitting RIP updates: for example, the interface might connect to a
network that is running a different routing protocol or to an external network.
However, other routers may still need to know how to reach this network.
To advertise a network that does not participate in RIP, do not enter the
network command for this network. Instead, redistribute connected routes
into RIP. The interfaces that run RIP will advertise routes for the network; the
interface that actually connects to the network, however, will not send or
receive RIP updates.
From the RIP configuration mode context, enter:
Syntax: redistribute connected [metric <value>]
You can specify the metric the router assigns to connected routes. If you do
not enter a value, the metric is 0.
