Cisco NX-OS/IOS BGP (Advanced) Comparison

'''Objective'''

This tech note outlines the main differences in advanced Border Gateway Protocol (BGP) support between Cisco® NX-OS Software and Cisco IOS® Software. Sample configurations are included for Cisco NX-OS and Cisco IOS Software for some common features to demonstrate the similarities and differences. Please refer to the [http://www.cisco.com/en/US/products/ps9402/products_installation_and_configuration_guides_list.html NX-OS documentation on Cisco.com] for a complete list of supported features.

'''BGP Overview'''

BGPv4 is a standard exterior routing protocol defined in RFC 4271, commonly used to exchange network reachability information between autonomous systems. This document discusses route reflectors, confederations, peer templates, route-map policies and the prefix-list (route-filtering) feature.

'''Important Cisco NX-OS and Cisco IOS Software Differences'''

In Cisco NX-OS:
* When configuring route reflectors, the '''route-reflector-client''' command is assigned per neighbor under the neighbor-specific address family.
* When configuring confederations, the confederation is configured under the autonomous system without the leading '''bgp''' keyword.
* Cisco NX-OS uses a peer template instead of a peer group to reuse common BGP policies.
* Multiple policy templates can be applied to a single neighbor. Cisco IOS Software allows only one policy template per neighbor.
* Cisco NX-OS does not require a manual reset for a neighbor when its routing policy is modified. Cisco IOS Software requires a hard or soft reset depending on the neighbor capabilities exchanged.

'''Things You Should Know'''

The following list provides some additional facts about Cisco NX-OS that should be helpful when designing, configuring, and maintaining an advanced BGP network configuration.

* Peer and session templates define neighbor attributes such as security passwords, timers, and transport options.
* Peer templates and session templates have identical configuration capabilities with one exception: peer templates can configure address families.
* Peer and session templates are inherited by a neighbor through the BGP neighbor configuration mode.
* Only one peer template and session template can be inherited by a single BGP neighbor.
* Peer templates can inherit session templates.
* Session templates can inherit other session templates.
* Policy templates define address-family policies for inbound or outbound polices, including default-route origination, filter lists, route-map polices, prefix lists, etc.
* Multiple policy templates can be assigned per neighbor. Policy templates are executed in order based on the configured sequence number.
* Policy templates are inherited by a neighbor through the neighbor and address-family configuration mode.
* Route-map polices can configure BGP attributes such as as-path, community lists, community attributes, dampening, local preference, metric type, origin, and weight.
* Route-map polices can be applied per neighbor for inbound and outbound routing policies.

'''Configuration Comparison'''

The following sample code shows the configuration similarities and differences between the Cisco NX-OS and Cisco IOS Software CLIs. The configurations are very similar with the exception of the hierarchy used in Cisco NX-OS.
