List, There's a document that's open for editing (at least for now) with a few sections of handy cli aliases the list may find useful; I'm assuming the vast majority of this list don't interactively log in to a router or have fully adopted sdn-centric management approaches, but for the rare times

Hiya, I'm confused. I have this new and shiny ASR9001 with IOS XR on it, with supposedly totally superior local services access control, and stuff. So, I configure: control-plane management-plane inband interface all allow all peer address ipv4 1.1.1.0/24 address ipv6 2001:1

Hi, The 'preempt delay' element means that it won't go active for xxx seconds _if_ there is a lower priority instance already visible. However - if the other instance is _not_ visible, then it goes active immediately. In your case, I suspect there was a layer-2 adjacency issue (maybe an STP re

Hi, Sure 802.17 RPR is meant to supersede the STP for loop avoidance, faster convergence and better BW efficiency. However in order to deploy it all nodes in the ring have to support it. All ME series switches should support it. Though I'd recommend upgrading the kit to MPLS capable ME switches
