[Xorp-users] Cannot start vif + IPv6 multicast question

Thank you for the info. The config file seems fine, so the problem
is somewhere else.
If you can send the "show interfaces" output that will be great,
because the information I have so far is not sufficient to track the
problem.

The reason you see the above error is probably because
HAVE_IPV6_MULTICAST_ROUTING is not defined inside your config.h (in
the top-level XORP directory). This is conditionally defined based
on various checks when ./configure is executed. To track the
problem, could you send me the output from ./configure and the
content of config.log file. The config.log file will appear in the
top-level XORP directory after running ./configure.

Pavlin
