VyOS CLI command set service ndp-proxy interface eth0 prefix 2001:db8::/64 mode 'static' Will generate the following NDP proxy configuration $ cat /run/ndppd/ndppd.conf # autogenerated by service_ndp-proxy.py # This tells 'ndppd' how often to reload the route file /proc/net/ipv6_route route-ttl 30000 # This sets up a listener, that will listen for any Neighbor Solicitation # messages, and respond to them according to a set of rules proxy eth0 { # Turn on or off the router flag for Neighbor Advertisements router no # Control how long to wait for a Neighbor Advertisment message before invalidating the entry (milliseconds) timeout 500 # Control how long a valid or invalid entry remains in the cache (milliseconds) ttl 30000 # This is a rule that the target address is to match against. If no netmask # is provided, /128 is assumed. You may have several rule sections, and the # addresses may or may not overlap. rule 2001:db8::/64 { static } }
