Command Reference Guide
update-source <interface>
Use the update-source command to specify which interface's IPv4 address will be used as the source IPv4
address for the Border Gateway Protocol (BGP) Transmission Control Protocol (TCP) connection (when
connecting to this peer). This command can be used for BGP neighbors on either the default or nondefault
VPN routing and forwarding (VRF) instance. Use the no form of this command to return to the default
setting.
Syntax Description
<interface>
Default Values
By default, the outbound interface's IPv4 address is used for BGP updates.
Command History
Release 9.3
Release 14.1
Release A4.01
Release 18.3
Functional Notes
The update-source command can be used to specify the source IP address for this BGP neighbor on
either the default or nondefault VRF instance. If the neighbor is to be created on a nondefault VRF
instance, the VRF instance must first be created using the command
page 1460. Once you have created the nondefault VRF instance, you can configure the BGP neighbor
settings for the VRF instance using the command
Configuration mode. For example, to configure the BGP neighbor characteristics for the nondefault VRF
instance RED1, enter the following commands:
(config)#vrf RED1 route-distinguisher ip 192.17.250.24:33
(config)#router bgp 100
(config-bgp)#vrf RED1
(config-bgp-vrf)#neighbor 10.20.1.1
(config-bgp-vrf-neighbor)#

Specifies the interface to be used as the source IPv4 address. Specify an
interface in the format <interface type [slot/port | slot/port.subinterface id |
interface id | interface id.subinterface id]>. For example, for a T1 interface,
use t1 0/1; for an Ethernet subinterface, use eth 0/1.1; for a PPP interface,
use ppp 1; for an ATM subinterface, use atm 1.1. Type update-source ?
for a complete list of valid interfaces.
Command was introduced.
Command was expanded to include the asynchronous transfer mode (ATM)
and high level data link control (HDLC) interfaces.
Command was expanded to include the Metro Ethernet Forum (MEF) Metro
Ethernet interface.
Command was incorporated into Multi-VRF BGP functionality.
