We are moving our retail environment to a frame relay DS-3. All our stores will be sub-interfaces. On the remote end (store side) we want to take advantage of EIGRP stubbing. I have enabled this at some test locations and still see a full routing table even though the stub looks like its working.
router eigrp 100
passive-interface default
no passive-interface Serial0/0.90
network 10.63.141.0 0.0.0.255
no auto-summary
eigrp stub summary
And the routing table for this router:
Gateway of last resort is 10.63.141.249 to network 0.0.0.0
10.0.0.0/8 is variably subnetted, 22 subnets, 3 masks

I am getting my injected default route care of the stub but why do I see all the other WAN routes, stub should hide these from my readings?

Hi
EIGRP stub doesn't prevent routes being advertised into the stub area - it prevents routes being advertised out of the stub area to the hub (as well as preventing the stub being queried for routes by the hub).
See this link:
Below fig 1 it explains this.
It often makes sense to strip down the routing tables a little - you can use a distribute list to allow just the routes you want (maybe just a default) to be advertised to the stubs.
Regards
Aaron
