BGP single prefix retrieval using netconf/yang

[thanhuwng]

Hi, I'm looking to get detail of a BGP prefix on IOS-XR router using netconf/yang similar to what the CLI "show bgp 1.1.1.1/32" achieves. So far I can't do that.

If I use the filter below

<bgp xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ipv4-bgp-oper">

<instances>

  <instance>

   <instance-name>default</instance-name>

    <instance-active>

     <default-vrf>

      <afs>

       <af>

        <af-name>ipv4-unicast</af-name>

        <networks>

         <network>

          <network>1.1.1.1/32<network/>

         <network>

        </networks>

       </af>

      </afs>

     </default-vrf>

    </instance-active>

   </instance>

</instances>

</bgp>

I get back all BGP ipv4 prefixes without detail on them.

If I use the filter below

<bgp xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ipv4-bgp-oper">

<instances>

  <instance>

   <instance-name>default</instance-name>

    <instance-active>

     <default-vrf>

      <afs>

       <af>

        <af-name>ipv4-unicast</af-name>

        <networks>

        </networks>

       </af>

      </afs>

     </default-vrf>

    </instance-active>

   </instance>

</instances>

</bgp>

I get all prefixes with detail of them.

Is there a way to retrieve detail of a single BGP prefix?

thanks

We have asked the responsible team about this and will get back to you shortly.

The network filter currently needs full key specification as shown below.  We have a ddts (CSCvf05647)  to support prefix filter with partial key in request.

<rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

  <get>
    <filter type="subtree">
      <bgp xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ipv4-bgp-oper">
        <instances>
          <instance>
 <instance-name>default</instance-name>
            <instance-active>
 <default-vrf>
              <afs>
               <af>
 <af-name>ipv4-unicast</af-name>
 <networks>
 <network>
 <rd>0000000000000000</rd>
 <network>192.168.28.5</network>
 <prefix-length>32</prefix-length>
 <af-name>ipv4</af-name>
 <process-instance-id>0</process-instance-id>
 </network>
 </networks>
               </af>
 </afs>
 </default-vrf>
            </instance-active>
          </instance>
        </instances>
      </bgp>
    </filter>
  </get>

Thanks Santiago. I couldn't get the full key spec filter to work, but understand there's a pending DDTS to make the partial key work so will wait until the fix is available.

thanks
