SBC Support for NNI Encryption

In this section:

Scenario

The SBC supports encryption across Network-Network Interfaces.

The requirements specified in the section "Background Information and Dependencies" under Minimal Out-Of-The-Box Configuration are met.
Ports and IP Interface Groups have been configured as described in NNI: Complex route selection.

SBC support for NNI encryption

Communication between servers within the core side of the network is typically trusted and usually clear-text/un-encrypted, even if it was originally encrypted at the edge.
On the interconnect side of the SBCs, the remote peers may or may not be trusted. Some interfaces maybe in clear text/un-encrypted, others may use IPsec or TLS to protect the interface. Scaling is much less of a concern than at the access side as there are typically far fewer peers.
