IP Routing

Routing Protocol Overview

Routing is the process of directing packets from a source node to a destination node along a path.

Routing Basics Configuration

This section describes basic functions used by various routing protocols, for example, the address prefix list and routing table.

IP Static Route

Static routes are mainly applied to simply-structured IP networks.

Dynamic Domain Name-based Routes

This section describes the concepts of dynamic domain name-based routes and how to configure it.

RIP

This section describes Routing Information Protocol (RIP) concepts and how to configure RIP, as well as provides configuration examples.

RIPng

RIPng is mainly applied to small and simply-structured IPv6 networks. RIPng is a routing protocol based on the distance vector and adopts the hop count to measure the distance to the destination.

OSPF

This section describes the basic concepts and configuration of Open Shortest Path First (OSPF) and provides OSPF configuration examples.

OSPFv3

By building Open Shortest Path First Version 3 (OSPFv3) networks, you can enable OSPFv3 to discover and calculate routes in ASs. OSPFv3 is applicable to a large-scale network that consists of hundreds of routers.

IS-IS

Intermediate System to Intermediate System (IS-IS) is an Interior Gateway Protocol (IGP) and runs at the link layer. IS-IS features rapid aggregation and a hierarchical structure. IS-IS is widely used on large-scale carrier networks.

IPv6 IS-IS

IS-IS supports multiple types networking layer protocols, including IPv6. In an IPv6 network, you can implement interconnection by configuring IS-IS.

BGP

BGP is used between ASs to transmit routing information on large-scale and complex networks.

BGP4+

BGP4+, which is applicable to the large-scale IPv6 network with a complicated structure, is used between ASs to transmit routing information.

Routing Policy

Routing policies are used to filter routes to change the path through which network traffic passes.
