Hi,
I'm working on a C3945e with a EHWIC-VA-DSL-M installed. It's configured as an Ethernet Interface
interface Ethernet0/2/0 description C3945e-1/Centurylink VDSL2 link ip address (PUBLIC_IP_HERE) 255.255.255.128 ip flow ingress ip nat outside ip virtual-reassembly in
I need to be able to send certain IPs out that path, and not the "default" path. I thought it'd be as simple as
ip route 1.1.1.1 255.255.255.255 Etherenet/0/2/0 (GATEWAY_IP_HERE)
But no. I tried without the (GATEWAY_IP_HERE), and no. Neither are showing up in the routing, and when I try to traceroute to 1.1.1.1 it'll go out the default route. I also tried to set
ip route (PUBLIC_IP_STARTING_IP) 255.255.255.128 Ethernet/0/2/0
But that didn't seem to help. It also doesn't show up in "show ip route", and when I add "longer-prefix" it'll just show the default route.
Where am I going wrong? Thanks

Ethernet0/2/0 <STATIC_PUBLIC_IP>YES NVRAM up down
The interface is up/down
So sure router not use it in rib.
Try
Do
Shut
No shut
Abd check if interface is up/up

This subnet 1.0.0.0 is in rib add to 0/2 interface
Is this same interface?

Gig0/2 is a different interface than Ethernet0/2/0 . Gig0/2 is the Starlink connection, I'm having issues with the Centurylink connection which is Ethernet0/2/0. None of the IPs associated with Ethernet/0/2/0 are in the routing table.

WTELFHH!!!!!
That's what I get for replying at 5:30a . I just blindly answered what was asked of me and didn't process it. There had been no notification that it was UP/DOWN. I wonder for how long!!
I tried it on the interface, nothing. So, figuring it was controlled by the VDSL (Which I also didn't realize was UP/DOWN) I shut and no shut it. And then was in for the longest 3 minutes of my life. The administrative connection went down. I couldn't ping, I couldn't do anything. Finally it came back. VDSL was in firmware download, and I lost contact again, for longer this time. I started to get ready to prepare an email about it being down when it pop'd back up again. In the rib, with routing, AND with track 2 coming up. UGH. Something so simple I totally overlooked because of ASSuM(E)ing.
Thanks.
