Neighbor’s AS number when extended capabilities are configured
Note: The AS number 23456 is a reserved 2-byte AS number. An old BGP speaker (2-byte implementation) should be configured with 23456 as its remote AS number while peering with a non-mappable new BGP speaker (4-byte implementation).
Default
By default, local as is disabled
