Route Policy Manager

The Route Policy Manager provides a route filtering capability in Cisco NX-OS. It uses route maps to

filter routes distributed across various routing protocols and between different entities within a given

routing protocol. Filtering is based on specific match criteria, which is similar to packet filtering by

access control lists. For more information, see Chapter 13, “Configuring Route Policy Manager.”

First-Hop Redundancy Protocols

A first-hop redundancy protocol (FHRP) allows you to provide redundant connections to your hosts. In

the event that an active first-hop router fails, the FHRP automatically selects a standby router to take

over. You do not need to update the hosts with new IP addresses because the address is virtual and shared

between each router in the FHRP group. For more information on the Hot Standby Router Protocol

(HSRP), see Chapter 14, “Configuring HSRP.” For more information on the Virtual Router Redundancy

Protocol (VRRP), see Chapter 15, “Configuring VRRP.”

Object Tracking

Object tracking allows you to track specific objects on the network, such as the interface line protocol

state, IP routing, and route reachability, and take action when the tracked object’s state changes. This

feature allows you to increase the availability of the network and shorten recovery time if an object state

goes down. For more information, see Chapter 16, “Configuring Object Tracking.”
