Hi,
I am following http://bdr-project.org/docs/stable/index.html for setting up multimaster replication.
First Master box
cat postgresql.conf
# Allow two other peer nodes, plus one for init_replica
max_replication_slots = 3
# Two peer nodes, plus two slots for pg_basebackup
max_wal_senders = 4
# Record data for logical replication
wal_level = 'logical'
track_commit_timestamp = on
# Load BDR
shared_preload_libraries = 'bdr'
# Make sure there are enough background worker slots for BDR to run
max_worker_processes = 10
# These aren't required, but are useful for diagnosing problems
#log_error_verbosity = verbose
#log_min_messages = debug1
#log_line_prefix = 'd=%d p=%p a=%a%q '
# Useful options for playing with conflicts
#bdr.default_apply_delay=2000 # milliseconds
#bdr.log_conflicts_to_table=on
# (BEGIN) BDR connection settings for node 1, port 5600
bdr.connections = 'secondarymasterport5601'
bdr.secondarymasterport5601_dsn = 'dbname=bdrdemo user=postgres port=5601'
# (END) BDR connection settings for node 1, port 5600
# (BEGIN) BDR connection settings for node 2, port 5601
#bdr.connections = '{DevEnvName}node01port5600'
#bdr.{DevEnvName}node01port5600_dsn = 'dbname={DevDBName} user=postgres port=5600'
#bdr.{DevEnvName}node01port5600_init_replica = on
#bdr.{DevEnvName}node01port5600_replica_local_dsn = 'dbname={DevDBName} user=postgres port=5601'
# (END) BDR connection settings for node 2, port 5601
cat postgresql.log

Please do let me know if anyone needs any information related to configs or logs.
Any help will be highly appreciable.
