Corosync configuration:

I have setup corosync with following ocnfiguration:

# cat /etc/corosync/corosync.conf
totem {
    version: 2
    secauth: off
    cluster_name: pacemaker1
    transport: udpu
    rrp_mode: passive

nodelist {
    node {
        ring0_addr: lvs1
        ring1_addr: lvs1b
        nodeid: 101
    node {
        ring0_addr: lvs2
        ring1_addr: lvs2b
        nodeid: 102

quorum {
   provider: corosync_votequorum
   two_node: 1
   wait_for_all: 1
   last_man_standing: 1
   auto_tie_breaker: 0

logging {
    to_logfile: yes
    logfile: /var/log/cluster/corosync.log
    to_syslog: yes
it works fine - both rings are fine:

# corosync-cfgtool -s
Printing ring status.
Local node ID 102
        id      =
        status  = ring 0 active with no faults
        id      =
        status  = ring 1 active with no faults
Question1: why corosync.conf manual says that interfaces in totem is required? I don't have it and cluster works fine.

       Within the totem directive, an interface directive is required.  There is also one configuration option which is required:

       Within the interface sub-directive of totem there are four parameters which are required.  There is one parameter which is optional.
I don't want to use any multicast - with my configuration when I run "tcpdump -n "broadcast or multicast or ip" -i eth2" it only catch only:

13:13:55.936454 IP > UDP, length 74
13:13:55.936677 IP > UDP, length 74
13:13:55.937025 IP > UDP, length 74
13:13:55.937253 IP > UDP, length 74
13:13:55.937593 IP > UDP, length 74
so looks fine.

I just want to be sure that there is no risk using configuration I have now.
