Hi Jim,
Can you please elaborate a bit more?
Since if I take the network command out of EIGRP on R14, the EIGRP adjacency will break
Mar 1 00:32:57.512 UTC: %DUAL-5-NBRCHANGE: IP-EIGRP 350: Neighbor 145.20.150.13
(Serial0/1) is down: interface down
Thanks.
Best Regards,
H.
Hey Hunt,
I confess that that I'm not 100% sure of the answer I'm about to give you
but perhaps, the groupstudy community will confirm or debunk my theory. So,
here goes:
In a static route, if you point it at an interface, the router considers it
a directly connected network with an Admin Dist = 0; when the static points
to the next-hop-address, the router considers it a static route with an AD =
1.
Now, here's the part I'm not positive about, but I suspect that when the
router goes to advertise it's route entries, the static route entry is
considered reduntant because the interface is already covered by the network
command. To test this theory, try reconfiguring the router so that network
between rtr 13 and 14 isn't included in your network command. Jim
