Frame relay multipoint ping problem

I always like troubleshooting. And you will know anything only after trouble
shooting the issue.

Here is a case when i had tried framerelay multipoint configuration , i met
a strange problem

I cant ping my own frame relay interface but from the other peers my interface
is pingable.

Just a google away i found the root of this issue!

Network Startup Resource Center

This is a nice website. I am always interested to know the history of todays network. Also what our veterans do in the networking field! These sort of Societies and Networking groups are  a real help.

They have got rich tutorials on different networking topics from network design to network technologies. A must recommended site for a new network engineer to look at.

The Network Startup Resource Center provides technical advice and engineering assistance to developing area networking initiatives seeking to connect to the public Internet, especially to academic/research institutions and non-governmental organizations (NGOs). There are numerous efforts in the less-connected countries of the world that have neither access to, nor funds for, private consulting assistance, particularly in universities and research institutes. We hope that our model of providing pro bono technical assistance to the locally based engineers, based on specific requests from them, increases the likelihood for establishing sustainable TCP/IP networks. The NSRC is not a funding agency and has no direct access to funding. Generally speaking, we are willing to help, or enlist other networking friends to help, with network architecture design, finding an appropriate international access provider, questions about routers/routing, DNS issues, hosting/mirroring web sites, organizing UNIX and TCP/IP training workshops, hosting engineering interns in US networks, building technical libraries, etc.

End of Support for RPS 675

Cisco Systems® announces the end-of-sale and end-of-life dates for the Cisco Redundant Power System 675 (RPS 675). The last day to order the Cisco RPS 675 is October 15, 2007. Customers with active service contracts will continue to receive support from the Cisco Technical Assistance Center (TAC) as shown in Table 1 of the EoL bulletin.

Customers are encouraged to migrate to the Cisco Redundant Power System 2300 (RPS 2300), which provides new and enhanced functionality, including active backup power for up to two routers and switches with Class 3 PoE on 48 ports, and additional management and configuration capabilities. The RPS 2300 also allows hot insertion of external devices and power supplies, thereby reducing potential down time. The RPS 2300 supports the new Cisco Catalyst 3750-E and 3560-E series switches, in addition to the Cisco Catalyst switches and Integrated Services Routers (ISR’s) supported by the RPS 675. In addition, the RPS 2300 uses the same modular 1150W AC and 750W AC power supplies used by the Cisco Catalyst 3750-E and 3560-E series switches. This consistency and modularity allow for common sparing, a lower mean time to repair, and greater configuration flexibility. Detailed information about the RPS 2300 can be obtained at: http://www.cisco.com/go/rps2300.

VPLS vs VLL <– MPLS technologies

I Love this article.. Long since i was searching for difference between VLL and VPLS. In simple terms VLL is point-to-point and VPLS is point-to-multipoint!

802.1x port authentication

You control the port authorization state by using the dot1x port-control interface configuration command and these keywords:

•force-authorized—disables 802.1X and causes the port to transition to the authorized state without any authentication exchange required. The port transmits and receives normal traffic without 802.1X-based authentication of the client. This is the default setting.

•force-unauthorized—causes the port to remain in the unauthorized state, ignoring all attempts by the client to authenticate. The switch cannot provide authentication services to the client through the interface.

•auto—enables 802.1X authentication and causes the port to begin in the unauthorized state, allowing only EAPOL frames to be sent and received through the port. The authentication process begins when the link state of the port transitions from down to up, or when an EAPOL-start frame is received. The switch requests the identity of the client and begins relaying authentication messages between the client and the authentication server. Each client attempting to access the network is uniquely identified by the switch by using the client’s MAC address.
