Time taken for NEW relay to be recognized by rest of network

Say I just set up a new relay, and it connects to other relays. Will it take any minimum time period for it to fully register with the network, before the BP node can produce blocks?

I ask because say one of my relays died, and I created a new one, with a new IP. Then connected it to my block-producing node. Will the BP node be able to produce blocks from the instant my new relay connects to other relays, or must the new relay’s IP become known to more of the network first?
