http://codereview.appspot.com/65047/diff/1/13#newcode40
Line 40: Ptr<Ipv4RoutingProtocol> ipv4rp = ipv4->GetRoutingProtocol ();
ipv4rp can't be null?

Should you put if (ipv4->GetRoutingProtocol () != 0) instead?

Line 97: // Add Ipv4ListRouting by default, with an Ipv4StaticRouting protocol
We must be careful when merging with my patch because I removed this
file:internet-stack.h/.cc. This should probably be moved to the
NotifyNewAggregate implementation in ipv4-l3-protocol.cc

Looks like a copy and paste code, can we do it in a cleaner way?

http://codereview.appspot.com/65047/diff/1/24#newcode142

Should we put a TODO in here and create a bug in the bug tracker to do it in the
future (of course if it is not altready on the bug tracker)

Faker, I accepted all of your comments, except the one about logging a bug in
the tracker for some of the XXX comments regarding multi-address not being
handled.  I will plan to file that bug at a later date.

Thanks,
Tom

+1 for merging.

ok, let's kill it.

DynamicCast<Ipv4StaticRouting> is your friend.

I liked the previous name better: Find makes it clear that this is a O(n)
operation, not O(1). Not a big deal either way.
