Server gets 0.0.0.0 Address when rebooting

By Cudmasters Los ·
I have a TS and DC. My TS uses the DC as DNS. When the servers restart, they get an ip address of 0.0.0.0. i have a 1800 series cisco router.

i have to do a route delete for the first 0.0.0.0 0.0.0.0 on the DC and TS to get the internet back. this is what it looks like. 10.1.10.4 is the TS and 10.1.10.1 is the router. This is the ipconfig


NetworkDestination Netmask Gateway Interface Metric

0.0.0.0 0.0.0.0 Onlink 10.1.10.4 266



0.0.0.0 0.0.0.0 10.1.10.1 10.1.10.4 266


10.1.10.0 255.255.255.0 On-link 10.1.10.4 266


10.1.10.4 255.255.255.255 On-link 10.1.10.4 266




there is more, thought this might be enough.

any thoughts


thanks

is this on your 1800?

your DC and TS ought to have static addresses.

If your configuring your 1800 static default gateway route, should be:
0.0.0.0 0.0.0.0 XXXX where XXXX is next hop router]or exit interface

if you can't ping the next hop router the static gateway of last resort won't show up in the route table. but will show up in the running config.

Static Addresses

they do. one is .3 and the other is .4

so if they have static addresses, where are you seeing

by CG IT In reply to Static Addresses

0.0.0.0 0.0.0.0 ???

if you run an ipconfig/all on the machines, should show static addresses. NICs don't simply reconfigure themselves.

on my first post is what i see. The problem is that there is two 0.0.0.0 0.0.0.0, the first one says onlink, the second gives the gateway. i have to do a delete route 0.0.0.0 0.0.0.0 to get rid of the onlink, then it works.

still not getting where you see the 0.0.0.0 0.0.0.0

by CG IT In reply to first post

one sees that in Cisco routing tables as the gateway of last resort route or default gateway route.

if your 1800 is changing it's gateway of last resort, then there is another device that is sending route updates to your 1800 saying that the gateway of last resort is 0.0.0.0 0.0.0.0 onlink.

when you create a static route for gateway of last resort or default gateway, the syntax is:

0.0.0.0 0.0.0.0 [next hop router] or exit interface [such as ethernet 0/0] and you have to be able to ping the next hop router for the route to work.

So I would look to see if your 1800 is allowing route updates via your WAN interface if you use a routing protocol like RIP.
