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 IPv6 BGP peer relationship 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 peer relationship cannot be established.
To enable 4-byte AS number suppression:

Enabling MD5 authentication for TCP connections
IPv6 BGP employs TCP as the transport protocol. To enhance security, configure IPv6 BGP to perform
MD5 authentication when establishing a TCP connection. If the authentication fails, no TCP connection
can be established.
The MD5 authentication for establishing TCP connections does not apply to BGP packets.
The MD5 authentication requires that the two parties have the same authentication mode and password
to establish a TCP connection; otherwise, no TCP connection can be established due to authentication
failure.
