Multicast and Routing Guide K/KA/KB.15.15

Modifying default metric for redistribution
The default metric is a global parameter that specifies the cost applied to all RIP routes by default.
The default value is 1. You can assign a cost from 1 to 15.
Syntax:
default-metric value
The value can be from 1 to 15. The default is 1.
Example:
To assign a default metric of 4 to all routes imported into RIP, enter the following
commands:
HP Switch(config)# router rip
HP Switch(rip)# default-metric 4
Enabling RIP route redistribution
The basic form of the redistribute command redistributes all routes of the selected type. For
finer control over route selection and modification of route properties, you can specify the
route-map parameter and the name of a route map. (For general information on route policy
and route maps, see “Route Policy” (page 205). For examples of using route maps in route
redistribution, see “Using route policy in route redistribution” (page 214).)
NOTE: Do not enable redistribution until you have configured the redistribution filters. Otherwise,
the network might become overloaded with routes that you did not intend to redistribute.
Syntax:
[no] router rip redistribute [ connected | static | ospf ]
[route-map name]
Enables redistribution of the specified route type to the RIP domain.
static Redistribute from manually configured routes.
connected Redistribute from locally connected networks.
ospf Redistribute from OSPF routes.
route-map name Optionally specify the name of a route-map to apply during
redistribution.
The no form of the command disables redistribution for the specified route type.
Example
To enable redistribution of all connected, static, and OSPF routes into RIP, enter the
following commands.
HP Switch(config)# router rip
HP Switch(rip)# redistribute connected
HP Switch(rip)# redistribute static
HP Switch(rip)# redistribute ospf
HP Switch(rip)# write memory
