With multipath enabled in RELENG_13 by default, I noticed that using my ppp scripts from previous releases no longer work as expected. In the past and according to the documentation,
If the add! command is used (note the trailing “!”), then if the
route already exists, it will be updated as with the ‘route change’
command (see route(8) for further details).
This instead adds an additional route to the FIB instead of overwriting the old one
default 10.255.255.1 UGS 6 1500 igb0
default 10.1.0.1 UGS 17 1500 tun10
restores the behaviour as described in the man pages
