One interface simply won't work...

Having issues routing on faste2/0

I made up IPs and put them in...mostly non-routable. If we put an IP address on the faste2/0 INT it will not work at all. However if we put the same IP on faste1/1 as a secondary all works fine. We are wondering why it won't work on faste2/0. If need more info let me know. Thanks

When you out in show interface fasteth2/0 what is the state up/up down/down especially for line protocol

otzispadmin · ‎06-13-2008

up/up

Everything on the router shows as fine, I just can't find what's wrong. Unless it's something small and I'm overlooking it.

I question whether it really works if you apply it as a secondary address. If you look carefully at the address:

ip address 127.233.225.1 255.255.255.0

network 127.x.x.x is a class A network that is reserved for loopback purposes.

It is evident that it would not work as a primary address since every device would treat 127.y.y.y as its own internal loopback and not send it to your device. And I would think that its behavior as a secondary address would be similar.

I know its loopback, I switched IPs so mine wouldn't show.

Just make up your own IP address'. We can take a secondary IP address move it to a different INT the router and switch both show a link, however nothing routes.

I just simply ran out of idea's.

I have been away for a bit and am following up on some things that were dormant, including your issue. I am not sure whether this is still an active issue for you. If it is it would be helpful if you would post the output of show arp. This would tell us what (if anything) is connected on that interface, and indirectly would verify the status of the interface.

The arpa shows all what it is suppose to show as in, IPs to MACs. I'm not sure now if it is the router or a switch issue. As the router should be working fine since both interfaces are copies of one another. I haven't had time to test for awhile as I have been busy.
