Redistribute
: You can have multiple routing protocols on a network, but you will need a method to exchange
routing information between the different protocols. This is done with redistribution. Redistribution is for more
than just between routing protocols, it is also useful for between routing protocols (RIP, OSPF), static routes can
be redistributed into a routing protocol, directly connected routes can be redistributed into a routing protocol,
etc.
The following type of routes exist and can be distributed by RIP:
Static
: Manually-defined (remote) routes. This tells RIP to forward static routes in addition to the
directly connected routes and the routes that have been learned from other RIP routers, which it
forwards by default.
Mode
: ___________________________________________________________________ .
Metric Value
: A RIP message includes a metric (number of hops) for each route.
Connected
: RIP can redistribute directly connected interfaces. RIP routes that correspond to defined IP
interfaces on which RIP is not enabled (defined locally). By default, the RIP Routing Table only includes
routes that correspond to IP interfaces on which RIP is enabled.
Mode
: ______________________________________________________________ .
Metric Value
: A RIP message includes a metric (number of hops) for each route.
OSPF
: Open Shortest Path First.
Mode
: ______________________________________________________________ .
Metric Value
: A RIP message includes a metric (number of hops) for each route.
Select
Auto
(default) or
Specific
. If
Specific
, enter a specific metric value. The valid range is 1 to
__. The default is 1 .
Default Metric Value
: ______________________________________________________________ .
Default Route
: At the dropdown select the default route to use.
Default Passive Mode
: Transmission of routing update messages over a specific IP interface can be disabled.
In this case, the router is passive, and only receives updated RIP information on this interface. By default,
transmission of routing updates on an IP interface is enabled.
Special address 0.0.0.0 is used to describe a default route. A default route is used to avoid listing every possible
network in the routing updates, when one or more closely-connected routers in the system are set to transfer
traffic to the networks that are not listed explicitly. These routers create RIP entries for the address 0.0.0.0, just
as if it was a network to which they are connected. You can enable the default route advertisement and
configure it with a given metric.
Administrative Distance
: AD is the “believability” of routing protocols. Routers measure each route source on
a scale of 0 to 255, where 0 is the best route and 255 is the worst route. The smaller the administrative distance
value, the more reliable the protocol. Typical administrative distances include: Directly connected=0, Static
route=1, OSPF=110, RIP=120, Unknown=255, etc.
