Chapter 38 Configuring IP Unicast Routing
Configuring ISO CLNS Routing
Beginning in privileged EXEC mode, follow these steps to configure IS-IS interface parameters:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify 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.
Step 3 isis metric default-metric [level-1 |
level-2] (Optional) Configure 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.
Step 4 isis hello-interval {seconds |
minimal} [level-1 | level-2] (Optional) Specify 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.
Step 5 isis hello-multiplier multiplier
[level-1 | level-2] (Optional) Specify 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.
Step 6 isis csnp-interval seconds [level-1 |
level-2] (Optional) Configure the IS-IS complete sequence number PDU (CSNP)
interval for the interface. The range is from 0 to 65535. The default is
10 seconds.
Step 7 isis retransmit-interval seconds (Optional) Configure 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.
Step 8 isis retransmit-throttle-interval
milliseconds (Optional) Configure 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 point-to-point links. The range is from 0 to
65535. The default is determined by the isis lsp-interval command.
Step 9 isis priority value [level-1 | level-2] (Optional) Configure the priority to use for designated router election. The
range is from 0 to 127. The default is 64.
Step 10 isis circuit-type {level-1 | level-1-2 |
level-2-only} (Optional) Configure the type of adjacency desired for neighbors on the
specified interface (specify the interface circuit type).
• level-1—a Level 1 adjacency is established if there is at least one area
address common to both this node and its neighbors.
• level-1-2—a Level 1 and 2 adjacency is established if the neighbor is
also configured as both Level 1 and Level 2 and there is at least one
area in common. If there is no area in common, a Level 2 adjacency is
established. This is the default.
• level 2—a Level 2 adjacency is established. If the neighbor router is a
Level 1 router, no adjacency is established.
