Question

You maintain a Python script that manages OSPF on Cisco IOS XE devices via RESTCONF (RFC 8040). A network engineer asks you to remove a single OSPF network statement (network 10.1.0.0 0.0.255.255 area 0) from process 1 without affecting any other OSPF configuration or restarting the process. The YANG data for that list entry is keyed by ip, mask, and area. Which approach correctly removes only that one statement?

Accepted Answer

Send an HTTP DELETE to the URL targeting the specific network list entry, encoding the ip, mask, and area keys in the path (e.g., .../ospf/process=1/network=10.1.0.0,0.0.255.255,0)

Answer

Send an HTTP PUT to the OSPF process resource with a payload that omits the unwanted network statement

Answer

Send an HTTP DELETE to the entire OSPF process resource (.../ospf/process=1) and then POST the remaining statements back

Answer

Send an HTTP PATCH to the OSPF process with an empty network list to clear all statements, then repopulate the desired ones
