Object

column r/w Enumeration
This field controls the operation of the alternative local
AS number specified by the bgpPeerConfAltLocalAs field.
It has no effect unless bgpPeerConfAltLocalAs specifies a
valid non-zero value.
              
This field controls the use of the alternative local AS
number in the following BGP operations:
-  establishing the peering session
-  updating the AS_PATH when importing a route received
   from the peer (EBGP only)
-  updating the AS_PATH when exporting a route to the peer
   (EBGP only).
              
These operations are described in full in the BGP
Configuration and Management Guide (bgp_config_mgmt.doc)
and summarized in the following table.
              
Mode        |Session   |AS_PATH In|AS_PATH Out
============+==========+==========+==================
Standard BGP|Primary AS|-         |Primary AS
Mode 1      |Either    |-         |Selected As
Mode 2      |Alt AS    |Alt AS    |Alt AS, Primary AS
Mode 3      |Alt AS    |-         |Alt AS, Primary AS
Mode 4      |Alt AS    |-         |Alt AS.
              
This field can be changed at any time.  However, if the
field is changed while the peer is admin_status UP, the
change will only take effect after the peer has been
cycled admin_status DOWN and then UP, thus forcing the
peer session to be restarted.  In this case, until the
peer is set admin_status DOWN, the peer will be marked as
out of date (as reported by the config_state field in the
AMB_BGP_PEER_STATUS row for the peer).
