All dynamic routing information is lost when there is a failure on the OA-780.
In this environment, it may be impossible to reach the system remotely from
multiple hops away in the network. The Lifeline Agent caches the dynamic/static
routing information during the Normal Mode of operation and uses this to provide
reachability in Lifeline Mode. However, static routing or additional configuration
may be required on the next hop router from the OA-780 system or other routers
on the path to the remote administrator. The Command Line Interface (CLI) allows
the configuration of additional routing information, that can be used when the
system goes to the Lifeline mode.

When there is a failure on the OA-780 and it switches to the Lifeline Mode, remote
in-band access
of the system is possible. This is an exclusive feature of the
OA-780. It enables the administrator to access the system using the same
network interface and the same IP address, which is in use when the system was
operating normally.
In addition to this,
out-of-band access
is also provided through the analog
modem built into the front panel of the OA-780 system. This feature is also not
available on most devices as they do not have dedicated hardware resources to
manage the device. In those that have separate control plane and data plane,
external modems are used on the console port - innately reducing the reliability of
out-of-band access drastically; an aspect that is crucial in times of emergency.
