Clearing BGP4+ information
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.
To perform a soft reset of a neighbor session and send ORFs to the neighbor, enter a command
such as the following.
BigIron RX(config)# clear ipv6 bgp nei peer_group1 soft in prefix-filter
Syntax: clear ipv6 bgp neighbor <ipv6-address> | <peer-group-name> [soft in prefix-filter]
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.
If you use the soft in prefix-filter keyword, the switch sends an updated IPv6 prefix list to the
neighbor as part of its route refresh message to the neighbor.
Closing or resetting a BGP4+ neighbor session
You can close a neighbor session or resend route updates to a neighbor. You can specify all
neighbors, a single neighbor, or all neighbors within a specific peer group or AS.
