Segment Routing provides mechanism to define end-to-end paths within a topology by encoding paths as sequences of sub-paths or instructions. These sub-paths or instructions are referred to as “segments”. IS-IS Segment Routing (henceforth referred to as IS-IS SR) provides means to advertise such segments through IS-IS protocol.

The Label Distribution Protocol (LDP) is a protocol in the Multiprotocol Label Switching (MPLS) context that allows label switch routers (LSRs) to exchange label mapping information. It is a distributed protocol without a central controller. Instead, each LSR generates local label mappings for Forward Equivalence Classes (FECs) and propagates this information to adjacent LSRs which it maintains LDP sessions with.

With this feature, IPv4 routes may be resolved via MPLS-over-GRE next-hop group to be able to push one MPLS label and then GRE encapsulate the resulting labelled IPv4 packet before sending out of the egress interface.

NAT peer state synchronization feature provides redundancy and resiliency for dynamic NAT across a pair of devices in an attempt to mitigate the risk of single NAT device failure. The main motivation is that since the NAT state is shared between two switches, the failure of one switch can be tolerated since the other switch will retain the translations.
