Hi, team!

After the peer ignore command is run on a Huawei device, does the device send a packet to notify peers that BGP peer relationships are interrupted?

Thanks.

Hi Steelbule,

When the bgp ignore command is used, the device sends a notification message first, and then the BGP peers send ACK messages to each other through TCP.

The process is as follows:

1.1.1.1 establishes a BGP peer relationship with 2.2.2.2 and then the bgp ignore command is used.

 bgp

The notification message is sent first.

bgp


Then 1.1.1.1 sends an ACK message with the fin bit set to 1 to 2.2.2.2.

bgp


In the end, 2.2.2.2 sends an ACK packet to 1.1.1.1.

bgp

Thanks!
