Hi,
One of my (HA) high availability application is trying to run 'openais'
on top of Linux bond0 (eth1 and eth2 are the slave interfaces) interface
but somehow fails to learn about the peer node. As such the two nodes
are able to communicate with each other. What I have observed that
'openais' attaches multicast address to the 'eth1' interface which is
actually the slave interface rather attaching it to the bond0 interface.
Following is the output of 'ipmaddr show ipv4' command:
1: lo
inet 224.0.0.1
3: eth0
inet 224.0.0.1
4: eth1
inet 226.94.1.1
inet 224.0.0.1
5: eth2
inet 224.0.0.1
6: eth3
inet 224.0.0.1
7: eth4
inet 224.0.0.1
8: eth5
inet 224.0.0.1
10: bond0
inet 224.0.0.1
Here, 226.94.1.1 is the 'openais' multicast address.
Following is the link which talks about multicast communication issue
with bond interface incase the multicast address is attached to the one
of the slave interfaces:

interface.html
Have any one noticed this issue before? Any clues??
With regards,
Vivek Gupta
