Understanding SCTP Multihoming
A Stream Control Transmission Protocol (SCTP) endpoint can be a multihomed host with either all IPv4 addresses or all IPv6 addresses. In Figure 1, endpoint A is connected to an SRX Series device with two IPv4 addresses, and endpoint B is connected to an SRX Series device with two IPv4 addresses. Therefore, endpoint A and endpoint B can set up an association using four different pairs of IP addresses, resulting in four valid paths for communication.

In Figure 2, endpoint A is connected to an SRX Series device with two IPv6 addresses, and endpoint B is connected to an SRX Series device with two IPv6 addresses. Therefore, endpoint A and endpoint B can set up an association using four different pairs of IP addresses, resulting in four valid paths for communication.
