restrictive assert in ECMP code
Last modified: 2014-08-26 14:12:26 EDT
Tommaso found that in the ipv4 global routing test suite, replacing the link n0->n2 with anything other than point-to-point causes this assert to fire:
SPFVertex::GetRootExitDirection () const
NS_ASSERT_MSG (m_ecmpRootExits.size () <= 1, "Assumed there is at most one exit from the root to this vertex");
return GetRootExitDirection (0);
This was added with the bug 667 ECMP patch many years ago. The assert may be too restrictive.
I'm filing this as a reminder to myself to investigate and fix.
