See thread: http://lists.quagga.net/pipermail/quagga-users/2007-May/008366.html

Quagga 0.99.7 will hit this assert:

2007/05/05 18:02:37 OSPF: Assertion `distance <= w->distance' failed in
file ospf_spf.c, line 440, function ospf_spf_add_parent

Occurs particularly when stub-routed routers are on the network, as this will
happen:

2007/05/06 19:03:39 OSPF: ospf_nexthop_calculation(): Start
2007/05/06 19:03:39 OSPF: V (parent): Router vertex 101.0.0.0 distance 65535
flags 0
2007/05/06 19:03:39 OSPF: parent 104.0.0.0 backlink 0 nexthop 10.133.4.1
interface eth0:10.133.4.2
2007/05/06 19:03:39 OSPF: W (dest) : Network vertex 10.133.1.1 distance 65535
flags 0
2007/05/06 19:03:39 OSPF: V->W distance: 65545
2007/05/06 19:03:39 OSPF: ospf_nexthop_calculation: Intervening routers, adding
parent(s)
2007/05/06 19:03:39 OSPF: Assertion `distance <= w->distance' failed in file
ospf_spf.c, line 440, function ospf_spf_add_parent

The problem is that vertices are initiliased to infinite cost (65536), so
topology > infinity (which we still want to be able to calculate, so that
stub-routed router can follow its own links) hits the assert.
