Description of problem: When the node routing information contains a multipath, the agent is unable to parse the link name and returns as error. This is caused by the agent not understanding the multipath data structure. Example: $>ip route show default via 10.19.32.254 dev ens1f0 proto dhcp metric 100 10.19.32.192/26 dev ens1f0 proto kernel scope link src 10.19.32.201 metric 100 10.88.0.0/16 dev cni-podman0 proto kernel scope link src 10.88.0.1 linkdown and $>ip -6 route ::1 dev lo proto kernel metric 256 pref medium 2620:52:0:1343::/64 dev ens1f0 proto ra metric 100 pref medium fe80::/64 dev ens1f0 proto kernel metric 100 pref medium fe80::/64 dev ens1f1 proto kernel metric 104 pref medium fe80::/64 dev ens4f0 proto kernel metric 105 pref medium fe80::/64 dev ens4f1 proto kernel metric 106 pref medium fe80::/64 dev cni-podman0 proto kernel metric 256 linkdown pref medium default proto ra metric 100 pref high nexthop via fe80::5054:ff:fefb:7f6d dev ens1f0 weight 1 nexthop via fe80::9e8a:cb00:6804:9200 dev ens1f0 weight 1 nexthop via fe80::200:5eff:fe00:201 dev ens1f0 weight 1 nexthop via fe80::9e8a:cb00:6804:ab00 dev ens1f0 weight 1 Version-Release number of selected component (if applicable): How reproducible: * Reproducible in a cluster with nodes that contain multipath IPv6 routes as shown above. Steps to Reproduce: 1. Create a node where the routing table has defined a multipath information for route balancing. 2. Agent will report back with an empty list of routing elements. Actual results: route structure contains no elements Expected results: route structure should contains all the routing elements. Additional info:
This is fixed in "release_tag":"v1.0.25.2"
