Hi,

I am using Confd6.3.1 and trying to use restconf on it.  
For this i have enabled the restconf in the confd.conf and i am able to fire the below query to identify the root:-

```
[viprasad@in-mvlb49 ConfdLogs]$ curl -i -u secadmin:Infinera#2 http://10.220.74.53:8008/.well-known/host-meta -H "Accept: application/yang-data+json" -X GET
HTTP/1.1 200 OK
Server: 
Date: Wed, 15 Mar 2017 09:56:00 GMT
Content-Length: 107
Content-Type: application/xrd+xml
Vary: Accept-Encoding

<XRD xmlns='http://docs.oasis-open.org/ns/xri/xrd-1.0'>
    <Link rel='restconf' href='/restconf'/>
</XRD>
[viprasad@in-mvlb49 ConfdLogs]$ 

```

After this when i fire the below query,it displays only the statictics info .But not the capabilities,schema info ,etc:-

```
[viprasad@in-mvlb49 ConfdLogs]$ curl -i -u secadmin:Infinera#2 http://10.220.74.53:8008/restconf/data -H "Accept: application/yang-data+json" -X GET

Hi,  
Got the issue .  
Actually there is a defect in Confd6.3.1 if we use candidate database along with running datastore writable which was the case of mine.  
I disabled the candidate database .Now its running fine.  
Thanks,  
Vivek Prasad

Hi,  
How to retrieve keyless list element via restconf

```auto
 container routes {
            description
              "Current content of the RIB.";
            list route {
              description
                "A RIB route entry. This data node MUST be augmented
                 with information specific for routes of each address
                 family.";
              leaf route-preference {
                type route-preference;
                description
                  "This route attribute, also known as administrative
                   distance, allows for selecting the preferred route
                   among routes with the same destination prefix. A
                   smaller value means a more preferred route.";
              }
              container next-hop {
                description
                  "Route's next-hop attribute.";
                uses next-hop-state-content;
              }
              uses route-metadata;
            }

```

I don’t know if this works with 6.3 that was released 5 years ago, but with ConfD 7.6 you can use the “limit” and “offset” query parameters.  
Example on how to get the second list-entry in a list:

```auto
Header: application/vnd.yang.collection+xml
Path: http://localhost:8008/restconf/data/ietf-routing:routing-state/routing-instance=default/ribs/rib="ipv4"/routes/route?offset=2&limit=1

```

Hi Cohult  
Your suggestion worked. How to retreive the specific element which comes under that list entries?

for ex: i wanted to retrieve route-preference of all the list entries.

Just use the RESTCONF standard “fields” parameter. Example:

```auto
http://localhost:8008/restconf/data/datamodel:routes/route?offset=0&limit=1&fields=route-preference

```

More “fields” parameter examples in the RESTCONF RFC [RFC 8040 - RESTCONF Protocol](https://datatracker.ietf.org/doc/html/rfc8040#appendix-B.3.3)
