Lab 3:  Troubleshooting
=======================
		
Location and content of dynamic routing log files:
		
For each dynamic routing protocol, the BIG-IP system logs messages to a file that pertains to the route domain in which the protocol is running. An example of the path name to a dynamic routing log file is /var/log/zebos/rd1/zebos.log file, where rd1 is the route domain of the protocol instance.
		
On E_A_BIGIP configure the following logging statement for BGP:
		
.. code-block:: none

    [root@E_A_BIGIP-13:Active:Standalone] log # imish
    E_A_BIGIP-13.local[0]>enable
    E_A_BIGIP-13.local[0]#conf t
    Enter configuration commands, one per line.  End with CNTL/Z.
    E_A_BIGIP-13.local[0](config)#log file /var/log/zebos/rd0/zebos.log
    E_A_BIGIP-13.local[0]#wr

    E_A_BIGIP-13.local[0]#
    E_A_BIGIP-13.local[0]#
    E_A_BIGIP-13.local[0]#exit
    
    On E_A_BIGIP configure BGP debugging:
		
.. code-block:: none

		E_A_BIGIP-13.local[0]#deb bgp all
		
.. code-block:: none

    E_A_BIGIP-13.local[0]#sh debug bgp
