The blog was updated. Correct link:
https://blog.benjojo.co.uk/post/bgp-path-attributes-grave-error-handling
The attribute was not malformed.
This is the hex dump of the attribute: “E0 1C 00”
It is described here.
https://www.rfc-editor.org/rfc/rfc6790#section-5.2
This attribute is deprecated, but that does not prevent routers from originating it or passing it on.

Kind Regards,
Jakob

Curious if anyone on the list is running VyOS and has experienced any problems?

Cheers,
