Hello.
QUESTION: In Nexus 9300, if there exists no route to 1.1.1.1, why is it not using default route, but instead using route to device originating EIGRP redistributed route for 1.1.1.1?
SITUATION: In remote backup datacenter, in the ASA there exists a static EIGRP redistributed route that allows the network to reach a remote subnet over a site-to-site VPN: ip route outside 172.16.3.0 255.255.255.0 1.1.1.1.
OK, but the network does not know how to get to 1.1.1.1; thus, I conclude the network devices will use the default routes that lead to the local gateways, not the backup datacenter ASA. I conclude I would need to add a route to 1.1.1.1 that pointed to the backup datacenter ASA.
BUT the data is showing that the devices are actually routing as I want-- to the remote datacenter ASA.
9K1# sh ip route
0.0.0.0/0, ubest/mbest: 1/0 *via 172.16.200.5 !!THIS IS THE DEFAULT ROUTE (to a different device than 172.16.200.1) . IT IS NOT BEING USED FOR THIS ROUTING (THOUGH IT SHOULD BE (?)) !!
9K1# sh ip eigrp topo 172.16.3.0/24
IP-EIGRP (AS 1): Topology entry for 172.16.3.0/24

Thank you.
