Unihomed configurations include two separate logical M2PA links that use different IP paths (see the following figure).

In the example shown in the following figure, each logical M2PA link is indicated with signaling link code SLC=0 and SLC=1.

If one of the IP paths fails, the respective SCTP association drops, the link drops, and MTP3 redistributes the traffic to the other links that are available within the same linkset. The path failure is visible in the Web UI as a link with M2PA State indicating NOT_INITIALIZED or OUT_OF_SERVICE (OOS).

Unihomed Configuration (Example)

 

The following figure shows the Web UI with the system provisioned for a unihomed configuration. In this configuration, the M2PA link uses one IP connection (Local IP Address 1). Local and remote IP Address 2 are not configured.
