2-byte AS numbers instead of 4 -byte AS numbers, the session cannot be established. To resolve this issue,
enable the 4-byte AS number suppression function. The device then sends an Open message to inform
the peer that it does not support 4-byte AS numbers, so the BGP session can be established.
If the peer device supports 4-byte AS numbers, do not enable the 4-byte AS number suppression function.
Otherwise, the BGP session cannot be established.

# In BGP view, enable 4-byte AS number suppression for peer 1.1.1.1.
