Hello, I have a problem with OSPF equal cost multi path. In my test, I noticed that ospfd had calculated two routes N 172.16.20.0/24 [30] area: 0.0.0.0 via 10.0.2.3, eth0 via 10.0.1.5, eth3 but none of them was written into the FIB by zebra O> 172.16.20.0/24 [110/30] via 10.0.2.3, eth0, 00:00:39 via 10.0.1.5, eth3, 00:00:39 I am now using quagga-0.99.6-01.fc5.mpls.1.955d.i386.rpm<http://downloads.sourceforge.net/mpls-linux/quagga-0.99.6-01.fc5.mpls.1.955d.i386.rpm?modtime=1174359745&big_mirror=0> downloaded from the mpls-linux website and I didn't enable ECMP when I compiled the kernel. I am expecting the behaviour that one of the equal cost routes be written in the FIB, what should I do? Thanks Yao |

This might be an error with the changes I have made to the FIB/RIB to suppo= rt MPLS. I would suggest trying the same test on a non-mpls version of quagga and see if you get the same results.

Hello, I've tried with quagga 0.99.7 without MPLS and I got the same result. I guess it's due to the inconsistency between the configuration of the kernel and that of quagga. Any comments are welcome. Thanks. 2007/6/25, James R.
