Enabling 4-byte AS number suppression
The device supports 4-byte AS numbers and uses 4-byte AS numbers by default. If the peer devices
support only 2-byte AS numbers, you must enable the 4-byte AS number suppression function on the
device.

Disabled by default
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.
Enabling quick EBGP session reestablishment
If the router receives no keepalive messages from a BGP peer within the holdtime, it disconnects from the
peer.
With quick EBGP connection reestablishment enabled, the router, when the link to a directly connected
EBGP peer is down, will reestablish a session to the EBGP peer immediately.
