UCARP not abiding by --nomcast flag
Last modified: 2013-11-15 17:39:01 EST
Description of problem:
The ucarp binary provides a flag, '--nomcast' which is supposed to prevent ucarp from using multicast and instead use broadcast.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Setup a VIP configuration, passing --nomcast to the ucarp binary
2. start the ucarp service
3. start tcpdump with the following filter 'multicast and host 22.214.171.124'
Packets are seen being sent to the Multicast address 126.96.36.199 (VRRP)
Packets should be sent via the broadcast address instead of via multicast according to the 'ucarp --help'
