I would think the redistribute connected command is the reason. Sent from my iPhone

By named I mean any networks that have been entered using the OSPF "network" command. In looking at a route table in one of the remote routers I see that it understands the existence of all networks back on the Core routers. On the Core routers some of the networks have not been added to the configuration with the command "network 172.32.112.0 0.0.0.255 area 0.0.0.0" (which I thought was necessary for the network to be advertised) yet the remote router knows of the existence of several networks that where never entered with the "network" command I also see where we have the following commands in the cores redistribute connected redistribute static Can anyone explain how/why the remote routers know of these networks??? Does the router ospf process automatically assume any network that is not listed with the "network" command but active belong to area 0 and is automatically advertised? Or are the redistribute commands having this effect? thnks in advance Walt Witkowski Primary Network Specialist - Sungard Higher Education Office of Information Technology - Delaware County Community College 610-359-5017(phone) / 610-359-4123 (fax)/856-217-4430(cell) <mailto:[email protected]>[email protected]<mailto:[email protected]> * --To unsubscribe from enterasys, send email to <mailto:[email protected]> [email protected]<mailto:[email protected]> with the body: unsubscribe enterasys Michael.D'[email protected]<mailto:Michael.D'[email protected]> * --To unsubscribe from enterasys, send email to <mailto:[email protected]> [email protected]<mailto:[email protected]> with the body: unsubscribe enterasys [email protected]<mailto:[email protected]> --- To unsubscribe from enterasys, send email to [email protected] with the body: unsubscribe enterasys [email protected]
