nixCraft Linux Sys Admin Blog

I’ve already written about Linux static routing configuration. However, sometime you need to configure Linux routers dynamically to get changes of network connections by communicating information about which networks each router can reach and how far away those networks are. These days most network admin prefer to use OSPF or BGP over RIP. Linux and UNIX system can act as router using special software.

Quagga Software

Quagga is a network routing suite providing implementations of OSPF (v2 & v3), RIP (v1, v2 & v3) and BGP (v4) for Unix-like platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quagga is a fork of GNU Zebra. Quagga is intended to be used as a Route Server and a Route Reflector. It is not a toolkit, it provides full routing power under a new architecture.

Zebra IP Routing Manager

zebra is an IP routing manager. It provides kernel routing table updates, interface lookups, and redistribution of routes between different routing protocols. zebra is included with quagga software.

Install quagga

Debian / Ubuntu Linux user type the following command:
$ sudo apt-get install quagga
RHEL , Fedora, CentOS Linux user type the following command:
# yum install quagga

quagga Software Configuration

quagga configuration is beyond the scope of this blog post; I recommend reading official configuration documentation for further information.

SAP To Roll Out ERP Linux Server Appliance

SAP and Intel , the world’s biggest makers of business software and microchips, will jointly offer servers pre-packaged with SAP software aimed at medium-sized firms, the two companies said.

SAP aims to provide customers with a 45% savings on implementation and a 25% savings on total cost of ownership over what they’d typically spend for a comparable hardware/software combo, said Jans Peter Klaey, president of global SME at SAP, in an interview.

The server is available in five Northern European countries and should reach 20 countries this year.
