2nd objective;

we can either use re-distrubtion, like re-distributing a static route, but then you might have other routes you do not wish to advertise so you have to filter ... turns abit of a headache (no default-information orginate command like OSPF :0(  )

likewise you could create a static 0.0.0.0 0.0.0.0 <next hop> and then put this into EIGRP via network 0.0.0.0, BUT this will advertise all networks!!! BE CAREFUL WITH THAT COMMAND

IP DEFAULT NETWORK

BB-Router(config)#ip default-network 192.168.1.0
BB-Router#show ip route

S*   192.168.1.0/24 is directly connected, Null0

 * - candidate default,

lets jump over and have alook at one of the other neighbours;


R3#  show ip route
Gateway of last resort is 10.1.34.1 to network 192.168.1.0

D*   192.168.1.0/24 [90/10511872] via 10.1.34.1, 00:04:03, Serial1/0

COOLIO, mission accomplished (not as kool as OSPF, but hey!)

... ONE THING TO NOTE! the network for this command HAS to be classful!?!?! ... so for this route it was okay as this was a class C network, but say we wanted a default route for one of the loopbacks ... 172.32.8.0/24, we would have to use a /16 - WEIRD?!?!? .. dont like this command!
