Group,

I was reading CCO site for rip default-metric but example is so lousy on web
site can't understand may be it's my problem. if some one explain with
example when to use default-metric in RIP while doing redistribution..I mean
we can assgin metric thorugh a route-map or in redistribute command..then
why do we need default metric...

thanks in advance.

 Usage Guidelines

The *default-metric* command is used in conjunction with the
*redistribute*router configuration command to cause the current
routing protocol to use
the same metric value for all redistributed routes. A default metric helps
solve the problem of redistributing routes with incompatible metrics.
Whenever metrics do not convert, using a default metric provides a
reasonable substitute and enables the redistribution to proceed.
Examples

The following example shows a router in autonomous system 109 using both the
RIP and the Open Shortest Path First (OSPF) routing protocols. The example
advertises OSPF-derived routes using RIP and assigns the OSPF-derived routes
a RIP metric of 10.

router rip

 default-metric 10

 redistribute ospf 109
