Changing the IPv4 address of a loopback interface

[ManiAm]

I am having trouble changing the ipv4 address of a loopback interface. Please take a look at Step23 in OSPF examples in here:

https://github.com/ManiAm/inet/blob/INETex/examples_INETex/routing_protocol_ospf/omnetpp.ini

Apparently changing the loopback address has no effect. Going through the configurator code, I noticed that the configurator iterates over topology.linkInfos and since there is no links attached to the loopback interface, it misses it.

inet/src/inet/networklayer/configurator/ipv4/Ipv4NetworkConfigurator.cc

Line 623 in b02af33

// configure address/netmask constraints on matching interfaces

Indeed, the NetworkConfiguratorBase class uses isLoopback() function throughout the code to avoid configuring loopback interfaces.

If we could up-vote features, then I would up-vote this one.
This is very useful in routing (ospf, BGP, etc.) scenarios when you want to test the propagation of a route into the network.
