New Revision: 243185
URL: http://svnweb.freebsd.org/changeset/base/243185
Log:
Add -fib modifier to specify FIB number. The FIB number can be in a
comma-separated list and/or range specification:
# route add -inet 192.0.2.0/24 198.51.100.1 -fib 1,3-5,6
Although all of the subcommands supports the modifier, "monitor" does not
support the list or range specification at this moment.
