Show IP Route Output

control

I done a show IP route and not to sure on the Output - See below.

RouterA#show ip route 172.25.10.0
Routing entry for 172.25.10.0/24
Known via "static", distance 1, metric 0
Redistributing via ospf 1
Advertised by ospf 1 subnets route-map red-test
Routing Descriptor Blocks:
* 172.27.20.70
Route metric is 0, traffic share count is 1

So from the above, I see this is a static route, manually entered?

What does the the following part refer to?
"Redistributing via ospf 1
Advertised by ospf 1 subnets route-map red-test"

Yes, this is a static route which was manually entered (as all static routes are).
The second part means that this static route is being redistributed into ospf – The subnets section means subnets are included in the redistribution (not just the classful networks) and all this is being filtered through a route map called “red-test”.
Hope that helps.

Thanks for that, all clear...apart from Route Map statement. Not familiar with them, so will read up a bit.

What is a route map used for, in easy to understand words..:)...?

Route maps are used for multiple policy options such as route filtering and policy based routing. You can chain severl permit and deny statements together with different match criteria.
