Claudio and crew,
When you enable OSPF-TE (http://tools.ietf.org/html/rfc3630) on a
Cisco router, OpenOSPFD crashes with "Invalid LSA type". Assuming you
have a functional setup, adding this (the last line) will recreate:
router ospf 1
mpls traffic-eng router-id Loopback0
mpls traffic-eng area 0
OpenBSD Log:

I have some sniffs if interested. .72 is a Cisco 7200, .10 is OpenBSD:
* Good: http://falz.net/static/ospfd-sniff-ok.pcap
* Bad: http://falz.net/static/ospfd-sniff-mpls-te.pcap
Of course also happens on other platforms (tested Juniper)
