Solved rtadvd not sending advertisement packets

[Farhan Khan]

Hi all,

I cannot get rtadvd(8) to begin to generate new packets. I have setup rtadvd.conf as follows:

epair7b:\
    :addr="fd07:7882:b0e3:6d27::"\
    :prefixlen#64\
    :tc=default\
    :rdns="2001:db8:53::1":

I am expecting to see rtadvd send out broadcast packets to ff02::1, but nothing is sent out. I am testing with tcpdump -i epair7b icmp6 and radvdump on a separate Linux machine.

Yes, I am running this in a jail. The epair7b interface is bridged to an external interface. Even within the machine nothing is sent out on epair7b or lo0, so I do not think this is a jail-issue.

Any ideas? Thanks.

Hi all, I just figured this out after a year. In short, I needed to add two things to /etc/rc.conf:

rtadvd_enable="YES"
rtadvd_interfaces="epair9b"

I did not see this documented anywhere, might be worth adding to the man page.
