Router Configuration Overview
In a 7210 SAS, an interface is a logical named entity. An interface is created by specifying an
interface name under the
configure>router context. This is the global router configuration
context where objects like static routes are defined. An IP interface name can be up to 32
alphanumeric characters long, must start with a letter, and is case-sensitive; for example, the
interface name “1.1.1.1” is not allowed, but “int-1.1.1.1” is allowed.
To create an interface on an Alcatel-Lucent 7210 SAS router, the basic configuration tasks that
must be performed are:
• Assign a name to the interface.
• Associate an IP address with the interface.
• Associate the interface with a system or a loopback interface.
A system interface should be configured.
System Interface
The system interface is associated with the network entity , not a specific interface.
The system interface is used to preserve connectivity (when routing reconvergence is possible)
when an interface fails or is removed. The system interface is used as the router identifier. A
system interface must have an IP address with a 32-bit subnet mask.
