Function:
Configure the update source. The “
no neighbor {<ip-address>|<TAG>}
update-source <IFNAME>
“ cancels this configuration
Parameter: <ip-address>
: Neighbor IP address
<TAG>
: Name of peer group
<IFNAME>
: Name or IP of the interface
Default:
Not configured, namely use nearest interface
Command Mode:
BGP route mode.
Usage Guide:
Specified update source is allowed to connect with any available interface which
normally is the loop back interface. The NO forms restores to the nearest interface update
source. Improper update source use may lead to neighbor connection unavailable, while the
invalid interface causes problem which is also the reasons we use loop back interfaces. Note:
the loop back interface should be maintained with its address accessibility to be able to establish
connections when as the update source.
Example:
Switch(config-router)#neighbor 10.1.1.66 update-source 192.168.0.1
1.8.3.73 neighbor version 4
Command: neighbor {<ip-address>|<TAG>} version 4
Function:
Configure the BGP version of the partner
Parameter: <ip-address>
: Neighbor IP address
<TAG>

Usage Guide:
Only version 4 is supported so far, so whatever the configuration is the version
remains at 4.
Example:
Switch(config-router)#neighbor 10.1.1.66 version 4
Switch(config-router)#
1.8.3.74 neighbor weight
Command: neighbor {<ip-address>|<TAG>} weight <0-65535>
no neighbor {<ip-address>|<TAG>} weight [<0-65535>]
Function:
Configure the route weight sent from the partner. The “
no neighbor
{<ip-address>|<TAG>} weight [<0-65535>]
” command restores the default value.

: Neighbor IP address.
<TAG>
: Name of IP address.
