RE: OT: UPLINKFAST versus BACKBONEFAST

Backbone fast is used to detect indirect link failures, whereas Uplink
fast is to guard against direct link failures.

While using backbone fast this feature needs to be configured on all the
switches for it to work effectively. Uplink fast just is to be
configured only on access switches and can work in isolation.

Backbonefast is used to bypass the max-age timer whereas uplinkfast is
for
bringing the NDP into forwarding immediately upon a failure of the ROOT
port.

They are 2 different things and one does not replace the other.

All,

I was reading about uplinkfast and backbonefast on CatOS. If I have
uplinkfast enabled on all my switches, would I ever need backbonefast
enabled also?
