bgpPeerAddrSourceIf

The interface index for the interface from which the
source address for session is chosen.  If non-zero, BGP
will look for the first address on this interface with a
type matching bgpPeerRemoteAddrType, and use that as the
source address.  If no matching address or interface
exists, or this field is set to zero, the source address
is chosen as described in bgpPeerLocalAddr.
              
This field is ignored for peers identified only by
interface (bgpPeerLocalAddr and bgpPeerRemoteAddr are both
zero).
              
This field can be changed at any time, causing the peer to
be immediately deactivated and reactivated.
              
If the configured interface (or address on that interface)
did not exist when the peer was activated, and is
subsequently added, the peer will automatically use the
configured interface address.  This will cause the peer to
be immediately deactivated and reactivated.
