Re: [netmod] [Netconf] Retrieving Information Pointed by leafref

Hi Per, This is a good news, but, please, help us out. Consider, we have a node - "te-tunnel" - which among other attributes has two key leafref lists: 1) each member of the 1st list points to a "connection" supporting the te-tunnel. All connections supporting all te-tunnels are stored in a

Re: [netmod] [Netconf] Retrieving Information Pointed by leafref

Just to be clear: what we're suggesting is that you can use the already-existing standard NETCONF XPath capability to achieve the desired result - see https://tools.ietf.org/html/rfc6241#section-8.9 --Per On 2017-10-09 21:52, Igor Bryskin wrote: I agree. For example, a leafref may point not to

Re: [netmod] [Netconf] Retrieving Information Pointed by leafref

I agree. For example, a leafref may point not to a singls entity, but to a list of entities, and the client might want to expand all of them into the joint get response. Igor From:Per Hedeland To:Martin Bjorklund, Cc:Igor Bryskin,xufeng.liu.i...@gmail.com,netc...@ietf.org,netmod@ietf.org,

> But as Per explained, it only works in some cases (when the leafref acts a "single pointer"). We think this is good enough. In all other cases leafref is simply not qualified for the expansion. I am not an expert , but I believe there is a similar capability in SQL, no? Igor -Original

Re: [netmod] [Netconf] Retrieving Information Pointed by leafref

Hi Per, Basically, what we need is a way for a client to request something like this: get joint with with a server interpreting the request as follows: if a node pointed by XPath contains a pointer (e.g. key leafref) matching one of the XPath from the "joint

Re: [netmod] [Netconf] Retrieving Information Pointed by leafref

I understand your use case, but a leaf of type leafref does not in general identify a single node in the data tree - the leafref path could be for a non-key leaf, and/or the path could traverse list nodes, and/or the "target" list could have multiple keys and thus multiple leafref-leafs be

Re: [netmod] [Netconf] Retrieving Information Pointed by leafref

I'm not sure that my XPath foo is good enough, but would NETCONF's XPath filter solve this problem? Thanks, Rob On 09/10/2017 14:42, Xufeng Liu wrote: Hi Per, *From:* Igor Bryskin [mailto:igor.brys...@huawei.com] *Sent:* Sunday, October 8, 2017 7:04 PM *To:* Igor Bryskin
