Load balancing over independent links
To load balance traffic between two E1 links to a remote network, you will need to set two routes
with equal cost. Both routes will have the same destination network and different interface (NET1,
NET2).

OUTING
The dynamic routing protocols RIP1, RIP2, and OSPF are configured using the command line
interface accessible from Menu-$E. The router CLI commands and parameters are documented in
appendix E.
NOTE: Standard LRU4240 includes RIP1, RIP2, and OSPF dynamic routing. BGP-4 protocol is available as an optional
dynamic routing protocol.

ONFIGURING
NAT
NAT allows the use of private IP addresses when accessing the Internet. Any host with unregistered
IP address must use NAT to communicate with the rest of the world. This service is transparent to
the internal local hosts.
In this documentation “Local” refers to unregistered IP addresses and “Global” refers to registered
IP addresses.
NAT bindings can be done statically, where a given local host may always map to a given global
address, or dynamically where the router assigns to the local host accessing the internet a global
address from the pool addresses given by the ISP.
The Dual Trunk E1 Router supports the following NAT features:
