Hyperledger Fabric: I would like to test the functionality of Anchor Peer, how can it be done?

Question

I would like to understand and test the functionality of Anchor Peer in the Hyperledger Fabric Network.

As per the documentation

Anchor Peer:Used to initiate gossip communication between peers from different organizations. The anchor peer serves as the entry point for another organization’s peer on the same channel to communicate with each of the peers in the anchor peer’s organization.

Does that mean, if I bring down the Anchor peer of ORG2 the transactions to peers of ORG2 will NOT be updated?

I have tried to do this practically. I have a channel mychannel where 2 peers from ORG1 and 2 peers of ORG2 participate. Where peer0 of both ORG are Anchor peers.

I brought down both Anchor peers and did transactions on peer1 of both org I expected that the changes might not reflect in other ORG but it does...

So my Question is: What is the basic role of Anchor peer? And How can I test it?

Thanks in Advance!

Answer 1

An anchor peer is just an entry in the config block of a channel, that helps peers of different organizations to know each other.

Once they learned about each other's endpoints - the anchor peer has no further use, unless the peers crash and are restarted.
