Configuring IP Router Parameters
14 Router Configuration Guide
• Creating an IP Address Range
• Autonomous Systems (AS)
• Confederations
• Proxy ARP
Refer to the Triple Play Guide for information about DHCP and support as well as
configuration examples for the 7750 SR and 7450 ESS.
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 for the 7750 SR or 7450 ESS
Network Domains
In order to determine which network ports (and hence which network complexes) are eligible
to transport traffic of individual SDPs, network-domain is introduced. This information is
then used for the sap-ingress queue allocation algorithm applied to VPLS SAPs. This
algorithm is optimized in such a way that no sap-ingress queues are allocated if the given port
does not belong to the network-domain used in the given VPLS. In addition, sap-ingress
queues will not be allocated towards network ports (regardless of the network-domain
membership) if the given VPLS does not contain any SDPs.
Sap-ingress queue allocation takes into account the following aspects:
• SHG membership of individual SDPs
• Network-domain definition under SDP to restrict the topology the given SDP can be
set-up in
