My question:I am trying to practice network automation and having a physical router i.e cisco 4321 and i have configured its interface gig0/0/1 as 192.168.1.3 . I have configured my laptop ethernet adapter configured with ip 192.168.1.1.
As per this link:Cisco DevNet: APIs, SDKs, Sandbox, and Community for Cisco Developers.
I have already enabled restconf and netconf on the router.
I am trying to make a Get request but getting 404 error. Would be glad if someone who had this kind of error can help me with this.
