Hi, Christian and Tony: Following your idea, the network will be filled with the large amounts of loop back addresses, will be one inextensible solution which has been discussed previously. And, once such loopack address failures, the nodes in other areas will also be notified. That is to

Happy New Year to All! Hi Peter, Top-pasting: In 99,99% of cases there will be only single pulse generated when one PE goes down. That itself is a very rare event itself. We can easily limit the number of pulses generated on ABR to a single digit number to cover the unlikely case of many PEs in

AFAIS this is a "operational and deployment" or "applicability" draft and not part of a protocol specification. But yes, such a draft would have value AFAIS, especially if it deals with both abstract node & reflection in one as available solutions. More than happy to attack that once the specs

[Lsr] Forklifts vs Flag Days

2022-01-03 Thread Christian Hopps
On a lighter note.. Forklift upgrades imply a requirement to replace hardware i.e., "get the forklift out to swap in/out huge heavy router chassis".. I think it's recently been somewhat misused to refer to software upgrades. SW upgrades do not require forklifts. :) "a Flag Day", would
