Hi Group,

I was trying out a few scenarios related to EIGRP stub routing. I am
refering to the below document from the Cisco site.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120
limit/120s/120s15/eigrpstb.htm

The document states that:

In the following example, the eigrp stub command is issued with the
connected and static keywords to configure the router as a stub that
advertises connected and static routes (sending summary routes will not be
permitted):
router eigrp 1
network 10.0.0.0
eigrp stub connected static
auto-summary (implicit)

I replicated the scenario but observed that summary route for local network
is advertised to the neighbors. Also, if I issue the "summary" option but
disable "auto-summary" within the EIGRP process, the subnet is advertised.

Now, what is the significance of "summary" option? I have similar
conflicting observation with the "connected" option as well.

Would appreciate some help in this matter and hope this doesn't turn out to
be a bug in the IOS.

Regards,
Pankaj K
