"Whenever you use the redistribute or the default-information router configuration command to redistribute routes into an OSPF routing domain, the Cisco IOS software automatically becomes an Autonomous System Boundary Router (ASBR)."
sometimes it is nessessary to generate a default route (0.0.0.0/0) for a network. An example would be a BGP router connected to the internet will not insert the whole internet routing table into OSPF but preferably a default route. The question is how to achieve this.
One option is f.e. through OSPF:
router ospf 10
default-information originate always
This will tell this router to generate a default route for the rest of the OSPF network. All traffic to the internet will follow the default route to the internet gateway and there you send the traffic to the prefered ISP, and so on.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
