Any `add' or `delete' command that uses MYADDR or HISADDR will be added to the sticky route list (show ipcp). When MYADDR or HISADDR change due to IPCP negotiations, and if `sroutes' is enabled (the default), all sticky route entries are updated in the routing table. The end result is that `add default hisaddr' will ``stick'', as will ``add myaddr 255.255.255.255 127.0.0.1'' and ``add 1.2.3.4 255.255.255.0 hisaddr''.
