Problem adding cluster node

[imapi]

Latest PVE 3.2 master has been set up:
root@virt6:~# pvecm status
Version: 6.2.0
Config Version: 10
Cluster Name: XXXX
Cluster Id: 19101
Cluster Member: Yes
Cluster Generation: 4
Membership state: Cluster-Member

Node name: virt6
Node ID: 1
Multicast addresses: 239.192.74.231

root@virt6:~#

When I try to add a node to cluster it failes:
root@virt5:~# pvecm add virt6.xxx.xx -force
can't create shared ssh key database '/etc/pve/priv/authorized_keys'
The authenticity of host 'virt6.xxx.xx (172.16.99.46)' can't be established.
ECDSA key fingerprint is 4b:60:99:93:9e:0e:0e:2c:6a:c0:a6:42:99:a1:1a:34.
Are you sure you want to continue connecting (yes/no)? yes
copy corosync auth key

Stopping pve cluster filesystem: pve-cluster.
backup old database
Starting pve cluster filesystem : pve-cluster.

Problem solved, by defaut multicasting IGMP was disabled on switch. Would be really nice to update the wiki pages to 3.X version.
