Re: [j-nsp] ospfv3 - JUNOS sends zero mtu in dbd - stuck in ExStart

I ran into this a few years ago. Even without going into the JUNOS implementation (they will probably tell you that this is works-as-designed, and that this was a conscious decision), this should not cause an issue in the OSPF session establishment. Per RFC 2328 section 10.6, If the

Hi Daniel, thank you for your reply. I've read the RFC now and you're right. I opened a bug report with quagga regarding this issue: https://bugzilla.quagga.net/show_bug.cgi?id=602 OSPFv3 on quagga seems to be a bit buggy in general, I'm still waiting for a fix of another problem (bug #600).

Hi, I'm having an issue with an OSPFv3 neighborship between Linux/quagga (0.99.16) and JUNOS (10.1R2.8 on SRX-100) via a standard ip-tunnel: the dbd info sent by JUNOS always contains mtu 0, which quagga does not like at all. This keeps my neighborship in ExStart. I set an ipv6 mtu on all
