Difference in deleting static route on XR between 0.5.1 and 0.7.0

Below is the simple Python code that should deletes static route on IOS XR:


    def create_RouterStatic_obj(arg_prefix,arg_prefixlen,arg_nexthop):


        router_static = Cisco_IOS_XR_ip_static_cfg.RouterStatic()


        vrf_unicast = router_static.default_vrf.address_family.vrfipv4.vrf_unicast

        vrf_prefix = vrf_unicast.vrf_prefixes.VrfPrefix()

        vrf_prefix.prefix = arg_prefix

        vrf_prefix.prefix_length = arg_prefixlen

        vrf_next_hop_next_hop_address = vrf_prefix.vrf_route.vrf_next_hop_table.VrfNextHopNextHopAddress()

        vrf_next_hop_next_hop_address.next_hop_address = arg_nexthop

        vrf_prefix.vrf_route.vrf_next_hop_table.vrf_next_hop_next_hop_address.append(vrf_next_hop_next_hop_address)

        vrf_unicast.vrf_prefixes.vrf_prefix.append(vrf_prefix)


        return router_static

    def delete_static_route(arg_prefix,arg_prefixlen,arg_nexthop):


        router_static = create_RouterStatic_obj(arg_prefix,arg_prefixlen,arg_nexthop)


        xr.ydk_crud.delete(xr.ydk_provider, router_static.default_vrf.address_family.vrfipv4.vrf_unicast.vrf_prefixes.vrf_prefix[0])


On YDK 0.5.1 it worked correctly, with following NETCONF message being sent:


<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:88ecc19c-3c07-4bb7-945d-cae4f3c1c810">

  <edit-config>

    <target>

      <candidate/>

    </target>

    <config xmlns:xc="urn:ietf:params:xml:ns:netconf:base:1.0">

      <router-static xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ip-static-cfg">

        <default-vrf>

          <address-family>

            <vrfipv4>

              <vrf-unicast>

                <vrf-prefixes>

                  <vrf-prefix xc:operation="delete">

                    <prefix>13.11.11.0</prefix>

                    <prefix-length>24</prefix-length>

                    <vrf-route>

                      <vrf-next-hop-table>

                        <vrf-next-hop-next-hop-address>

                          <next-hop-address>100.100.100.100</next-hop-address>

                        </vrf-next-hop-next-hop-address>

                      </vrf-next-hop-table>

                    </vrf-route>

                  </vrf-prefix>

                </vrf-prefixes>

              </vrf-unicast>

            </vrfipv4>

          </address-family>

        </default-vrf>

      </router-static>

    </config>

  </edit-config>

</rpc>


However, on YDK 7.0 it deletes all static routes. Message sent reveals that "delete" is now in the <router-static> level:


<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

<edit-config xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

  <target>

    <candidate/>

  </target>

  <error-option>rollback-on-error</error-option>

  <config><router-static xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ip-static-cfg" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" nc:operation="delete">

  <default-vrf>

    <address-family>

      <vrfipv4>

        <vrf-unicast>

          <vrf-prefixes>

            <vrf-prefix>

              <prefix>13.11.11.0</prefix>

              <prefix-length>24</prefix-length>

              <vrf-route>

                <vrf-next-hop-table>

                  <vrf-next-hop-next-hop-address>

                    <next-hop-address>100.100.100.100</next-hop-address>

                  </vrf-next-hop-next-hop-address>

                </vrf-next-hop-table>

              </vrf-route>

            </vrf-prefix>

          </vrf-prefixes>

        </vrf-unicast>

      </vrfipv4>

    </address-family>

  </default-vrf>

</router-static>

</config>

</edit-config>

</rpc>


Is this a bug in YDK-Py or client code should be changed?

The client code needs to be changed. Please see this example for how to delete lists in YDK 0.7.+ :
