@jimp when your will fix it?

jimp

There isn't enough information to say what exactly is wrong yet, and we haven't been able to reproduce any crashes here so far. So there is no ETA on a fix.

2.5.0 is under development, it's not expected to be stable at this point.

yon 0

@jimp That could be from the RADIX_MPATH / multipath options we enabled in the kernel and FRR on 2.5.0 to allow for multi-path/ECMP routing. It's entirely possible the code doesn't work as well as it should, since it's not as heavily tested.

maybe should check this.

i had try use frr vtysh shell add two openvpn ipv6 address , it still down too. So i think the pf frr with openvpn has bug.

@jimp said in Frr with use two ipv6 BGP Neighbors openvpn Update Source:

2.5.0 is under development, it's not expected to be stable at this point.

your try frr get two ipv6 full table upstream. why only has one ipv6 upstream is normal work.

frr and system bug

@jimp i try setup use openbgpd normarl work ipv6 with openvpn. so i think the frr sure has bugs.

frr v7.2 is out, we need for upgrade?

i need edit this, when frr got two or more and ipv4 or ipv6 full route tables from neighbors via openvpn update Source, then frr will down.

yon 0

The results of repeated tests should be that there is a problem with the system, which has an impact on multiple BGP software, but it has the greatest impact on frr, causing the system to be paralyzed.
