I had P router previous enable the LDP with other peer routers. No password is configured for the peers session. No neighbour command.
Now I would like to add more routers and connect to this P routers via STM-1. But new requirement is the LDP session must setup password for this new peers, for existing peers remain no password set.
If I add this command in P router, will it cause other non-password peer to down ? or it just take effect only the new peer ?
