ospf link-protection
Open, MediumPublic


Follow up from a conversation with @faidon.

As routers already have "load-balance per-packet" configured. The only needed step is to add the statement "link-protection" under 'protocols ospf[3] <interface>" for each cross DC links (most likely to get cut).

Then confirm the correct backup route is properly installed by looking at "show ospf backup spf" as well as "show route forwarding-table destination xxx".

We could also lower the BFD timers (currently waits for 3*300ms to consider a link down) to speed up failover on the MX routers. Depending on how fast we want failover to happen.

This task has been assigned to the same task owner for more than two years. Resetting task assignee due to inactivity, to decrease task cookie-licking and to get a slightly more realistic overview of plans. Please feel free to assign this task to yourself again if you still realistically work or plan to work on this task - it would be welcome!

For tips how to manage individual work in Phabricator (noisy notifications, lists of task, etc.), see for available options.
