Hi all,

I gone through the following config.Its using ospf protocol
which enough for routing the data.BUT WHY A STATIC ROUTE HAS BEEN CONFIGURED IN ADDITION TO OSPF.

Pls help.

Cheers,

not quite sure what the question is here. what interface are you concerned with?

 

[wybnormal]

The static router of 0.0.0.0 0.0.0.0 serial1/0 means that any packet that the router doesnt have a route for.. even with OSPF, will go out the serial port to the next available router and let it worry about it.

If OSPF were to drop off line for any reason, this would pick up the slack. While OSPF is online, there are route entries which takes precedence over this route unless there is not a match.
