Configuring The Interface Bandwidth - Juniper JUNOS OS 10.4 - FOR EX REV 1 Manual

Configuring the Interface Bandwidth

Copyright © 2010, Juniper Networks, Inc.
You assign a 128-bit IPv6 address to an interface by including the
address aaaa:bbbb:...:zzzz/nn;
You can include this statement at the following hierarchy levels:
[edit interfaces interface-name unit logical-unit-number family inet6]
[edit logical-systems logical-system-name interfaces interface-name unit
logical-unit-number family inet6]
The double colon ( ) represents all bits set to 0, as shown in the following example:
::
interfaces fe-0/0/1 {
unit 0 {
family inet6 {
address fec0:1:1:1::2/64;
}
}
}
NOTE: You must manually configure the router or switch advertisement and
advertise the default prefix for autoconfiguration to work on a specific
interface.
By default, the Junos OS uses the physical interface's speed for the MIB-II object,
You can configure the logical unit to populate the
bandwidth value for the logical interface. The
informational-only parameter; you cannot adjust the actual bandwidth of an interface
with this statement.
NOTE: We recommend that you be careful when setting this value. Any
interface bandwidth value that you configure using the
affects how the interface cost is calculated for a dynamic routing protocol,
such as OSPF. By default, the interface cost for a dynamic routing protocol
is calculated using the following formula:
cost = reference-bandwidth/bandwidth,
where bandwidth is the physical interface speed. However, if you specify a
value for bandwidth using the
calculate the interface cost, rather than the actual physical interface
bandwidth.
To configure the bandwidth value for a logical interface, include the
bandwidth rate;
