This field is used in conjunction with bgpPeerAsOverride to indicate whether BGP should perform AS-override on routes advertised to the peer. If AS-override is enabled, then when advertising routes to this peer for this address-family, any instance of the peer's AS number will be replaced in the advertised AS path with the local AS number. The peer may be configured to ignore this field and instead obtain the value from a peer-group as explained in the table description. AS-override may be enabled independently for each address family. When bgpPeerAsOverride is set to 'true', set bgpPeerAfiSafiAsOverride to 'true' or 'false' to enable or disable as-override for each address family. This field can be changed at any time, and may cause routes to be re-advertised to or withdrawn from the peer. Note that this field has no effect when set for iBGP peers.
