New Revision: 234436
URL: http://svn.freebsd.org/changeset/base/234436
Log:
Add multiple FIB support to route(8). An -fib <fibnum list> option has been
added to specify the target FIBs. The <fibnum list> is a comma-separated
list of FIB numbers and/or a range of FIBs like the following:
# route add -inet 10.1.1.0/24 192.168.2.1 -fib 2,4,6
# route add -inet 10.1.1.0/24 192.168.2.1 -fib 0-3,5,7-8
