The debugging bgp packet update command enables debugging of BGP update packets.
The undo debugging bgp packet update command disables debugging of BGP update packets.
By default, debugging of BGP packets is disabled.

Usage Scenario
The debugging bgp packet command enables debugging of BGP packets so that you can view the information during BGP packet receiving and sending.
When much information is output, you can filter the output information by VPN instance, peer, and address family.Follow-up Procedure
Run the undo debugging bgp packet command to disable debugging.
Precautions
Debugging information is output on the screen. Do not output too much information for other purposes than debugging so that the performance is not affected.
