Summary
This document describes how to clear or remove a Border Gateway Protocol (BGP) configuration.
Requirements
The following items are necessary to perform this task:
• Administrative/shell/root access to the NetScaler
• Basic understanding of UNIX commands
• Access to the NetScaler command line prompt
Procedure
- Log on to the NetScaler with full administrative privileges.
- Enter the shell command.
- CD to the nsconfig directory: cd /nsconfig. Verify the file existence.
root@ns# cd /nsconfig
root@ns# ls –l
-rw-r----- 1 root wheel 259 Oct 25 11:56 ZebOS.conf
-r--r--r-- 1 root wheel 731 Aug 10 22:13 inetd.conf - Remove all the ZebOS.conf files (if there are more than one):
root@ns# rm -r ZebOS* - Reload the NetScaler.
- If you do not want to reload the NetScaler, kill and restart the processes related to BGP.
Important!: This step should only be completed by a skilled system administrator because of the potential for serious problems. Use this step at your own risk. - Find the respective processes:
root@ns# ps -aux |grep Zeb
root 375 0.0 0.1 2592 1016 ?? Is 2:41AM 0:00.01 /netscaler/nsm -d -f /nsconfig/ZebOS.conf
root 5684 0.0 0.1 3160 2088 ?? S<s 11:34AM 0:00.02 /netscaler/bgpd -d -f /nsconfig/ZebOS.conf
root 6070 0.0 0.0 1016 600 p1 R+ 11:59AM 0:00.00 grep Zeb - Kill the process by using kill -9 <pid>
root@ns# kill -9 375
root@ns# kill -9 5684 - Restart those processes by entering the same commands from the ps command.
root@ns# /netscaler/nsm -d -f /nsconfig/ZebOS.conf
root@ns# /netscaler/bgpd -d -f /nsconfig/ZebOS.conf - Make sure that the process are running again:
root@ns# ps -aux |grep Zeb
root 6137 0.0 0.1 2580 1480 ?? Ss 12:02PM 0:00.00 /netscaler/nsm -d -f /nsconfig/ZebOS.conf
root 6144 0.0 0.1 3080 2020 ?? Ss 12:03PM 0:00.00 /netscaler/bgpd -d -f /nsconfig/ZebOS.conf
root 6147 0.0 0.0 1012 592 p1 R+ 12:03PM 0:00.00 grep Zeb - If the process does not restart, you need to reload.
- Configure BGP via >vtysh again and save it.
