- Routing Protocols Guide
  This guide describes how to configure unicast routing protocols (OSFP, IS-IS, BGP, RIP) and multicast routing protocols (IGMP, MLD, PIM, MSDP) supported on the 7705 SAR.
- Services Guide
  This guide describes how to configure service parameters such as service access points (SAPs) and service destination points (SDPs), Layer 2 and Layer 3 services, security functions (IPSec), and encryption functions (NGE) on the 7705 SAR.
- System Management Guide
  This guide describes how to configure system security and access features, SNMP functionality, and event and accounting logs on the 7705 SAR.

MKA

Each MACsec peer operates the MACsec key agreement (MKA). Each node can operate multiple MKAs based on the number of CAs the node belongs to. Each MKA instance is protected by a distinct secure CAK, which allows each port authentication entity (PAE) to ensure that information for an MKA instance is only accepted from other peers that also possess that CAK, identifying the peers as members or potential members of the same CA. See MACsec static CAK for information about the CAK identification process performed via the CKN.

Note: For an MKA session to establish, the MTU configured in the network must be as large or larger than the size of the MACsec control plane signaling messages. The size of these signaling messages depends on a number of factors, such as the number of peers and the cipher suite selected.
