Ah, I did. Probably some caching issues somewhere. Thanks for the job! 11 Jan. 2019 г., 2:04 Donald Sharp <sharpd@cumulusnetworks.com>:
I did before I sent this email. Perhaps you should hit f5

On Monday a research group installed into the global BGP routing table a prefix with a attribute type of 0xFF, which is designated as experimental by BGP RFC's. FRR had a developmental escape that read this attribute incorrectly and caused the bgp peering session to flap. If you have compiled FRR with the `--enable-bgp-vnc` option and run BGP as a peer on the global routing table you are vulnerable to this issue. This issue has been fixed in FRR with this commit:
https://github.com/FRRouting/frr/commit/943d595a018e69b550db08cccba1d0778a86...
We have applied this fix to the stable/3.0(3.0.4), stable/4.0(4.0.1), stable/5.0(5.0.2) and stable/6.0(6.0.2) branches. New releases can be found here:
https://github.com/FRRouting/frr/releases/tag/frr-3.0.4 https://github.com/FRRouting/frr/releases/tag/frr-4.0.1 https://github.com/FRRouting/frr/releases/tag/frr-5.0.2 https://github.com/FRRouting/frr/releases/tag/frr-6.0.2
Snap packaging and the FreeBSD ports have been updated as well. We recommend you update your installation of FRR immediately.
At this point we are applying for a CVE and will announce that information when we have it.
In the near future we plan to implement RFC-7606 to handle this situation better in BGP, if you have any questions please feel free to email me, or to open up discussions on the frog alias.
thanks!
