Enabling 4-byte AS number suppression
When a switch that supports 4-byte AS numbers sends an Open message for peer relationship
establishment, the Optional parameters field of the message indicates that the AS number occupies four
bytes—in the range of 1 to 4294967295. If the peer device does not support 4-byte AS numbers (for
examples, it supports only 2-byte AS numbers), the peer relationship cannot be established.
After you enable the 4-byte AS number suppression function, the peer device can then process the Open
message even though it does not support 4-byte AS numbers, and the BGP peer relationship can be
established.
Follow these steps to enable 4-byte AS number suppression:

NOTE:
If the peer device supports 4-byte AS numbers, do not enable the 4-byte AS number suppression function;
otherwise, the BGP peer relationship cannot be established.
