MP-eBGP Configuration

Some information on how to configure multiprotocol extended Border Gateway Protocol (MP-EBGP). Extended BGP allows for the transport of routing information for multiple network layer protocols IPv6, VPNv4, and others. MP-BGP allows you to have a unicast routing topology different from a multicast routing topology, which helps to control the network and resources.

In this example, the R1 and R3 routers are configured to be in AS 5500 forming iBGP. The R2 router is configured to be in AS 6500. The R1 and R2 routers communicate with each other using MP-EBGP.

More BGP next-hop-self

From the below you can see the next hop for network is which is outsite of 65000 AS, and router jazz doesn’t have a route to it.  BGP will not put into routing table because it doesn’t know how to reach next hop, you can see this below:

BGP-Next Hp Self 2

BGP-Next Hp Self 3

BGP-Next Hp Self 4

By adding the next-hop-self command on the router owen it will change the next-hop attribute for external networks that will be advertised to the router Jazz:

owen(config-router)#neighbour next-hop-self

BGP-Next Hp Self 4.5

This changes the next hop attribute from to be on the router owen

BGP-Next Hp Self 5

from Jazz you can now ping ( on Jules.

BGP-Next Hp Self 6

FlashPlayer for Iceweasel

What is Iceweasel?

Iceweasel is a fork [from Firefox] with the following purpose :

  1. backporting of security fixes to declared Debian stable version.

  2. no inclusion of trademarked Mozilla artwork (because of #1 above)

Beyond that, they will be basically identical.

Step # 01
Launch the browser and download the Flash Player in a separate folder.
Download link =
(Note: Version to download tar.gz for other Linux)

Step # 02
Launch the terminal and open the folder path where downloaded flash file is stored then run the following command.

Code: tar xzvf install_flash_player_11_linux.i386.tar.gz


Code: tar xzvf install_flash_player_11_linux.x86_64.tar.gz

If in case your downloaded file having some another name then put that file name during extracting

Code: tar xzvf yourdownloadedfilename.tar.gz

Step # 3
Now run the following last command (Remember: Do not change the folder path stay in the same folder where you unpacked the files)

Code: cp /usr/lib/mozilla/plugins/

Unlocking a 3G SIM while in the Router

A really useful command for unlocking the SIM while in the router.

router#sh cell 0/1/0 security
Card Holder Verification (CHV1) = Enabled
SIM Status = Locked
SIM User Operation Required = Enter CHV1
Number of Retries remaining = 3

router#cellular 0/1/0 gsm sim unlock NNNN
!!!WARNING: SIM will be unlocked with pin=NNNN(4), call will be disconnected!!!
Are you sure you want to proceed?[confirm]
