Configuring IP Router Parameters
In order to provision services on an Alcatel-Lucent router, logical IP routing interfaces must be
configured to associate attributes such as an IP address, port or the system with the IP interface.
A special type of IP interface is the system interface. A system interface must have an IP address
with a 32-bit subnet mask. The system interface is used as the router identifier by higher-level
protocols such as OSPF and BGP, unless overwritten by an explicit router ID.
The following router features can be configured:
• Interfaces on page 20
• Creating an IP Address Range on page 24
• Autonomous Systems (AS) on page 37
• Confederations on page 38
• Proxy ARP on page 40
Refer to 7750 SR OS Triple Play Guide for information about DHCP and support as well as
configuration examples. on page 33
Interfaces
Alcatel-Lucent routers use different types of interfaces for various functions. Interfaces must be
configured with parameters such as the interface type (network and system) and address. A port is
not associated with a system interface. An interface can be associated with the system (loopback
address).
Network Interface
A network interface (a logical IP routing interface) can be configured on one of the following
entities:
• A physical or logical port
• A SONET/SDH channel
