Jim,
The following config additions will accomplish what you are looking
for:
system {
default-address-selection;
}
interfaces {
lo0 {
unit 0 {
family inet {
address 127.0.0.1/32;
address 123.123.123.123/32 {
primary;
}
}
}
}
}
Unfortunately, the default-address-selection affects the source
address of all packets leaving the route engine. It can be kind of
confusing at first. Commands like ping, traceroute, telnet, and
ssh all use the loopback address as the source by default. Finally
in Junos 5.x there is now a "source" option on these commands to
set a specific source address.
