Clearing BGP4+ information
45
•
Reset a session to send and receive Outbound Route Filters (ORFs).
•
Close a session, or reset a session and resend/receive an update.
•
Clear traffic counters.
•
Clear route flap dampening statistics.
Clearing BGP4+ neighbor diagnostic buffers
You can clear the following BGP4+ neighbor diagnostic information in buffers:
•
The first 400 bytes of the last packet that contained an error.
•
The last NOTIFICATION message either sent or received by the neighbor.
To display these buffers, use the last-packet-with-error keyword with the show ipv6 bgp neighbors
command. For more information about this command, refer to
“Displaying last error packet from a
BGP4+ neighbor” on page 1160.
You can clear the buffers for all neighbors, for an individual neighbor, or for all the neighbors within
a specific peer group or AS.
To clear these buffers for neighbor 2000:e0ff:37::1, enter the following commands at the Privileged
EXEC level or any of the Config levels of the CLI.
BigIron RX# clear ipv6 bgp neighbor 2000:e0ff:37::1 last-packet-with-error
BigIron RX# clear ipv6 bgp neighbor 2000:e0ff:37::1 notification-errors
Syntax: clear ipv6 bgp neighbor all | <ipv6-address> | <peer-group-name> | <as-number>
last-packet-with-error | notification-errors
The all | <ipv6-address> | <peer-group-name> | <as-num> specifies the neighbor. The
<ipv6-address> parameter specifies a neighbor by its IPv6 address. You must specify this address
in hexadecimal using 16-bit values between colons as documented in RFC 2373. The
<peer-group-name> specifies all neighbors in a specific peer group. The <as-num> parameter
specifies all neighbors within the specified AS. The all keyword specifies all neighbors.
The last-packet-with-error keyword clears the buffer containing the first 400 bytes of the last packet
that contained errors.
The notification-errors keyword clears the notification error code for the last NOTIFICATION
message sent or received.
Resetting a BGP4+ neighbor session to send and receive ORFs
You can perform a hard or soft reset of a BGP4+ neighbor session to send or receive ORFs. For
more information about cooperative filtering, refer to the “Configuring BGP4” chapter in the
Router
Configuration Guide .
To perform a hard reset of a neighbor session and send ORFs to the neighbor, enter a command
such as the following.
BigIron RX# clear ipv6 bgp neighbor 2000:e0ff:38::1
This command resets the BGP4+ session with neighbor 2000:e0ff:38::1 and sends the ORFs to
the neighbor when the neighbor comes up again. If the neighbor sends ORFs to the switch, the
switch accepts them if the send capability is enabled.
