Purpose
Configures padding on IS-IS hello PDUs for an IS-IS
interface on the router.
• Hello padding applies to only this interface and
not to all interfaces.
Specifies the length of time between hello packets that
the software sends.
Specifies the number of IS-IS hello packets a neighbor
must miss before the router should declare the
adjacency as down.
• A higher value increases the networks tolerance
for dropped packets, but also may increase the
amount of time required to detect the failure of
an adjacent router.
• Conversely, not detecting the failure of an
adjacent router can result in greater packet loss.
Specifies that this system include authentication in the
hello packets and requires successful authentication
of the hello packet from the neighbor to establish an
adjacency.
(Optional) Displays IS-IS adjacencies.
(Optional) Displays a log of the most recent adjacency
state transitions.
