Purpose
Specifies the interface to be configured and enter interface
configuration mode. If the interface is not already configured
as a Layer 3 interface, enter the no switchport command to
put it into Layer 3 mode.
(Optional) Configures the metric (or cost) for the specified
interface. The range is from 0 to 63. The default is 10. If no
level is entered, the default is to apply to both Level 1 and
Level 2 routers.
(Optional) Specifies the length of time between hello packets
sent by the switch. By default, a value three times the hello
interval seconds is advertised as the holdtime in the hello
packets sent. With smaller hello intervals, topological changes
are detected faster, but there is more routing traffic.
• minimal—causes the system to compute the hello
interval based on the hello multiplier so that the resulting
hold time is 1 second.
• seconds—the range is from 1 to 65535. The default is
10 seconds.
(Optional) Specifies the number of IS-IS hello packets a
neighbor must miss before the router should declare the
adjacency as down. The range is from 3 to 1000. The default
is 3. Using a smaller hello-multiplier causes fast convergence,
but can result in more routing instability.
(Optional) Configures the IS-IS complete sequence number
PDU (CSNP) interval for the interface. The range is from 0
to 65535. The default is 10 seconds.
(Optional) Configures the number of seconds between
retransmission of IS-IS LSPs for point-to-point links. The
value you specify should be an integer greater than the
expected round-trip delay between any two routers on the
network. The range is from 0 to 65535. The default is 5
seconds.
(Optional) Configures the IS-IS LSP retransmission throttle
interval, which is the maximum rate (number of milliseconds
between packets) at which IS-IS LSPs will be re-sent on
