Dear Community,
I am manually trying to onboard a 4331 onto our SDWAN Fabric. I am in the process of getting the underlay configured (WAN IP, Default Route, DNS server etc.). I have dozens of these in the past with no issues. However, this router is having an issue. Eventhough I have entered the WAN IP, Default Router and DNS servers, the router is unable to resolve URL's. The router is in Controller Mode. This will cause the router to not be able to resolve the vbond URL. When I try to ping www.cisco.com (or any URL) I get the following error:
Router#ping www.cisco.com
% Unrecognized host or address, or protocol not running.
I am able to ping out to the internet though:
Router#ping 8.8.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 6/6/8 ms
Router#
Any ideas?

I believe you need to specify the DNS servers to be used with the ip name-server {ip address} command.
03-01-2024 02:48 PM
This should make it work, or adjust to your internal DNS servers.

Device has IP reachability to Internet and but does not resolve the DNS resolution.
ip name-server 8.8.8.8 187.102.222.46
i can see the DNS name server configured.
% Unrecognized host or address, or protocol not running
But i do not see domain-lookup config ?
Try add domain lookup and test it :
ip domain-lookup
Hope that help you.

Hey everyone, sorry for the late response. This ended up being an ISP issue with them filtering traffic. Once they made changes to their ACL's the router was able to resolve URLs.
