!!! Below is a default route to null 0 with an admin distance of
!!! 10 that is tracked by DELAY and a default route to demand 1
!!! with admin distance of 200
ip route 0.0.0.0 0.0.0.0 null 0 10 track DELAY
ip route 0.0.0.0 0.0.0.0 demand 1 200
Since track DELAY is in a pass state during the first 180 seconds after the SROS unit has booted up, the
default route to null interface 0 will be in effect and all traffic using the default route in the route table will be
routed to null interface 0. The demand interface will not be activated during the first 180 seconds because
the default route to null interface 0 has a lower administrative distance than the demand interface default
route.
As soon as a default route has been assigned to the primary Ethernet WAN interface, the route will appear
in the routing table with an administrative distance of 1 (which is lower than the administrative distance of
10 for the null interface). Due to the lower administrative distance, all traffic using the default route in the
route table will switch to the default route associated with the primary Ethernet interface.
180 seconds after boot up, the schedule DELAY-AFTER-BOOT becomes active. Subsequently, track
DELAY fails. The default route to null interface 0 is removed from the routing table and will not be placed in
the route table again as long as the SROS unit is up. The two default routes that remain are the current
default route to the primary WAN Ethernet interface (administrative distance is 1) and the back-up default
