From: Claudio Jeker cje...@diehard.n-r-g.com Thanks for the log and tcpdumps. It seems you're the first person to try opaque LSA against ospfd. Can you give the following diff a spin? I think this will solve the problems. Claudio, Thanks for the patch. I've compiled this in a lab and indeed

OpenOSPFD crashes when using mpls traffic-eng on Cisco

2012-03-25 Thread Chris Wopat
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

OpenBGPD 4.9 ignoring MED?

2011-06-13 Thread Chris Wopat
Is there a known issue with OpenBGPD ignoring MED during its path selection? Note that the first item listed is best below and it has a MED of 12. The others are 10 which should be preferred over 12. I'm guessing that it's then going to a later stage of path selection where it's choosing hte
