Lxd Cluster with juju

First created lxd bridge (lxc network create lxdbr0) then assigned that bridge through lxd init for all nodes. is there any difference between dynamically or manually created a bridge network?

@jameinel please have a look for this ans.

this is my bridge network details from juju5 node in the cluster:

root@juju5:~# lxc network show lxdbr0
config:
  ipv4.address: 10.78.54.1/24
  ipv4.nat: "true"
  ipv6.address: none
  ipv6.nat: "true"
description: ""
name: lxdbr0
type: bridge
used_by: []
managed: true
status: Created
locations:
- juju1
- juju5

but when i am trying to bootstrap in juju5 node from juju1 node it is showing following debug output:

Attempting to connect to 10.78.54.137:22
10:52:09 DEBUG juju.provider.common bootstrap.go:576 connection attempt for 10.78.54.137 failed: ssh: connect to host 10.78.54.137 port 22: No route to host

and also it is possible to create normal lxc container in the cluster two nodes. but making problem when i am using juju.
totally confused here, how should I continue here !!!

@rick_h is there possible any kind of help ?
