Add NDP Proxy Daemon to the
docker-orchagentimage, and manage it withsupervisord.- Why I did it
Native proxy NDP in Linux requires explicit neighbor entries in the kernel neighbor table, i.e. it's not possible to configure a subnet for proxy NDP. NDP Proxy Daemon (
ndppd) bypasses the kernel neighbor table entirely and allows for subnets when configuring proxy NDP.- How I did it
ndppdduring image build, and copy config files to imagendppdoutput tologgerinside container to log output in syslog- How to verify it
docker-orchagentimage to a device that supportsproxy_arp.proxy_arpfor a VLAN interface in config_db.swsscontainer.config reloadip -6 neigh. The IPv6 address pinged in step 7 should beREACHABLE.- Which release branch to backport (provide reason below if selected)
- Description for the changelog
Add support for proxy NDP
