By using ACIToolkit, I know using epg.attach(vmm) to attach the VMM to a EPG. However, how to change the Deployment type and Resolution as well?? Any example?

Here's sample to construct "mpls ldp" config and mpls ldp sync under ospf: def config_ospf(provider, keys, router_info, ospf): .. .. .. name_scope = area_area_id.name_scopes.NameScope() name_scope.interface_name = interface_name if interface_ospf_ldp=="Y": name_scope.ldp_sync=True <<<<< def config_mplsldp(provider, keys, router_info, mplsldp): lines=read_interface_files() connected_router=router_info[12] interface_mpls_ldp_config=mplsldp.default_vrf.interfaces.Interface() for line in lines: p=line.split(",") if p[0]==connected_router: # Create router_id interface_name=p[1] ipv4addr, netmask = cidr_to_netmask(p[2]) interface_mpls_ldp=p[7] if interface_name=="Loopback0": mplsldp.default_vrf.global_.router_id=ipv4addr else: if interface_mpls_ldp=="Y": interface_mpls_ldp_config.interface_name=interface_name interface_mpls_ldp_config.enable=Empty() mplsldp.default_vrf.interfaces.interface.append(interface_mpls_ldp_config) mplsldp.enable=Empty() # create configuration on NETCONF device crud.create(provider, mplsldp)

Hi Einar, It works when the interface is "admin shutdown". However, if the interface is up, I can't use this method. It causes me an additional step to check the interface status first before issuing this. Is it possible to "no shutdown" the interface without query the interface status?? Many Thanks!! ====================================== ydk.errors.YPYServiceProviderError: Server rejected request. error-type: application error-tag: data-missing error-severity: error error-path: ns1:interface-configurations/ns1:interface-configuration[active = 'act' and interface-name = 'GigabitEthernet0/0/0/0']/ns1:shutdown

May I know how to "no shutdown" the interface?? I can only find the interface_configuration.shutdown=empty() to explicitly shutdown the interface but can't find a function to explicitly no shutdown the interface. Many Thanks!

I'm working on an PoC for ASR9K. And would like to demonstrate how to program the MPLS-te tunnel. First thing first, I want to know how to program the LDP like the CLI below?? any sample config?? I saw there is a Cisco_IOS_XR_mpls_ldp_oper module and Cisco_IOS_XR_mpls_ldp_cfg module but donno how to use it... example: router ospf 1000 log adjacency changes network point-to-point area 10 mpls traffic-eng <<<<< interface Loopback0 passive enable ! interface GigabitEthernet0/0/0/0 cost 1 mpls ldp sync <<<<< ! interface GigabitEthernet0/0/0/1 cost 1 mpls ldp sync ! ! mpls traffic-eng router-id Loopback0 ! mpls ldp <<<<<< router-id 10.1.11.1 interface GigabitEthernet0/0/0/0 ! interface GigabitEthernet0/0/0/1 ! interface GigabitEthernet0/0/0/2 !

Can we update the interface ip address as <ip address>/<netmask> instead of seperateing in primary.address and primary.netmask?? If so, what does the syntax look like?

How to retrieve the interface configuration?? I saw the "nc-read-xr-ifmgr-cfg-11-ydk.py", the process is just "pass" def process_interface_configurations(interface_configurations): """Process data in interface_configurations object.""" pass I tried to modified a bit but I got the response "None". def process_interface_configurations(interface_configurations): """Process data in interface_configurations object.""" int=interface_configurations.InterfaceConfiguration() print ('interface name: ',int.interface_name) I believe it should be a list of configuration... but don't know how it should be... any sample can be reference??? Thanks a lot!!
