This page lists things that need to be done for IPv4 and routing protocols.

Bugs and cleanup

• IpForward attribute (ipv4.cc) doesn't do anything
• Ipv4L3Protocol::GetStaticRouting() needs to be deleted
• in general, Ipv4L3Protocol needs a lot of cleanup, and bugs/limitations documented in the tracker
• Ipv4L3Protocol needs a unit test
• some XXXs remain around the multi-address (ip aliasing) code
• case 4) of Ipv4L3Protocol::Send() is not implemented
• should some of the routing protocol interfaces be aggregated to node? Not clear.

New features needed

• Tunneling net device (Ipv4 in ipv4)
• Netlink-like routing API
• Public API to look at the ARP cache
• Multicast group membership, and non-source-specific multicast
• Ability to dump routing tables for logging/output
• helpers to provide iproute2-like interface
