Ospf Configuration - Huawei S6700 Series Configuration Manual

S6700 Series Ethernet Switches
Configuration Guide - IP Routing
About This Chapter
OSPF, which is developed by the IETF, is a link-state IGP. OSPF is widely used in access
networks and MANs.
4.1 OSPF Overview
OSPF is a link-state IGP. At present, OSPFv2 is intended for IPv4.
4.2 OSPF Features Supported by the S6700
The S6700 supports various OSPF features, including multi-process, authentication, hot standby,
Smart-discover, TE, DS-TE, VPN multi-instance, BFD, and GTSM.
4.3 Configuring Basic OSPF Functions
This section describes how to configure basic OSPF functions.
4.4 Configuring OSPF on the NBMA or P2MP Network
This section describes how to configure OSPF and modify attributes on the NBMA or point-to-
multipoint (P2MP) network to flexibly construct the OSPF network.
4.5 Configuring an OSPF Route Selection Rule
You can configure an OSPF route selection rule to meet requirements of complex networks.
4.6 Controlling OSPF Routing Information
You can control the advertising and receiving of OSPF routing information and import routes
of other protocols.
4.7 Configuring an OSPF Stub Area
Configuring a non-backbone area as a stub area can reduce routing entries in the area in an AS
does not transmit routes learned from other areas in the AS or AS external routes. This reduces
bandwidth and storage resource consumption.
4.8 Configuring an NSSA
Configuring a non-backbone area on the border of an AS as an NSSA does not transmit routes
learned from other areas in the AS but imports AS external routes. This reduces bandwidth and
storage resource consumption on the switch.
4.9 Configuring BFD for OSPF
After BFD for OSPF is enabled, when a link fails, the switch rapidly detects the failure, notifies
the OSPF process or interface of the fault, and instructs OSPF to recalculate routes. This speeds
up OSPF network convergence.
