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">

<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?
