EIGRP stub

[ccnpninja]

I read that the EIGRP stub router should have a default route to the core router. Do I need to configure it manually? or is it created after I issue an "eigrp stub" command under "router eigrp..." ?

You need to configure it manually. You would generally create a default-route or supernet route on the core router and then advertise this to the EIGRP stub router.

So if I issue a "ip summary-address eigrp 30 0.0.0.0 0.0.0.0" on the core router, the EIGRP stub will get it as part of an EIGRP update, and it will install a default route through the core?

Is there another way to advertise the default-route from the core? What about "ip default-network"?

You could even just use a default static ip route eg.

ip route 0.0.0.0 0.0.0.0

and redistribute into EIGRP process.

But if you use this or you use ip default-network then you still need to use a distribute-list under the eigrp configuration to make sure only the default-route is sent to the stub router.

If you use the summary-address as in your example then because this is an interface command EIGRP will advertise the summary route only which is exactly what you want.
