N Commands > neighbor update-source

neighbor update-source

Description: 

Allows a BGP session to use the IP address of any operational interface as the source address of TCP connections used by BGP. The no version restores the interface assignment to the closest interface.

NOTE: Removing an interface that was specified in this command effectively removes this command from the router configuration as well.

Syntax: 

neighbor { ipAddress | peerGroupName } update-source
{ interfaceType interfaceSpecifier | updateSourceAddress }

no neighbor { ipAddress | peerGroupName } update-source
[ interfaceType interfaceSpecifier | updateSourceAddress ]

• ipAddress—IP address of BGP-speaking neighbor
• peerGroupName—Name of a BGP peer group. If you specify a BGP peer group by using the peerGroupName argument, all the members of the peer group inherit the characteristic configured with this command, unless it is overridden for a specific peer.
• interfaceType—Interface type; see Interface Types and Specifiers in About This Guide
• interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers in About This Guide
• updateSourceAddress—Source IP address
