Multihoming with SailFin - Traffic separation

There are quite a few multi home use cases that can be accomplished with SailFin clusters, this article descirbes how intra-cluster traffic can be isolated on a specific network. High availability in SailFin can be achieved by deploying a cluster of instances and configuring the load balancer and the replication modules as per the user's needs. Apart from the basic configuration of these modules, SailFin (2.0) also allows users to separate the intra-cluster traffic (resulting from the load-balancer, replication and the group management service modules) from the external traffic, which allows users to maintain/configure their network in way that best suits their traffic needs. Traffic separation also allows the users to plan their network and augment certain parts of it when required. This following steps describes how SailFin 2.0 can be configured on multiple interfaces (IP addresses), The instructions assume that the user wants to separate the cluster internal traffic (CLB and GMS only) from the external SIP/Http traffic (from the UAs). Machine setup: In order to separate the traffic, the machines should have atleast 2 IP addresses, which ideally would belong to different networks. There are different ways of multi-homing a system which are out of scope of the discussion here. For the sake of simplicity we would assume the machine on which this configuration is...
