> IOS XR said "hey look that's bad, and I'm going to ignore it", and Brocade said, "hey that's bad, and you're bad so I'm not going to talk to you", I think the Junipers reacted much as IOS XR did, but that doesn't mean there wasn't a bad message.
I can confirm the Juniper reaction, it got marked as "invalid" with
unreachable next hop. I don't think it threw an actual error, just put
it in the naughty pile and ignored it.
