Configuring BGP4+ graceful restart

Configuring BGP4

graceful restart

BGP4+ Graceful Restart (GR) can be configured for a global routing instance or for a specified

Virtual Routing and Forwarding (VRF) instance. The following sections describe how to enable the

BGP4+ Graceful Restart feature.

NOTE

Graceful restart is not supported for multicast. Only IPv4 and IPv6 are supported.

BGP4+ Graceful Restart is fully supported by Brocade MLX series and Brocade NetIron XMR

devices. The Brocade NetIron CER and Brocade NetIron CES devices only support helper mode.

State The state of the session with the neighbor. The states are from the

perspective of this device of the session, not the perspective of the

neighbor. The state values are based on the BGP4 state machine values

described in RFC 1771 and can be one of the following for each device:

• IDLE – The BGP4 process is waiting to be started. Usually, enabling

BGP4 or establishing a neighbor session starts the BGP4 process.

• A minus sign (-) indicates that the session has gone down and the

software is clearing or removing routes.

• ADMND – The neighbor has been administratively shut down.

• A minus sign (-) indicates that the session has gone down and the

software is clearing or removing routes.

• CONNECT – BGP4 is waiting for the connection process for the TCP

neighbor session to be completed.

• ACTIVE – BGP4 is waiting for a TCP connection from the neighbor.

NOTE: When the state frequently changes between CONNECT and

ACTIVE, there may be a problem with the TCP connection.

• OPEN SENT – BGP4 is waiting for an Open message from the

neighbor.

• OPEN CONFIRM – BGP4 has received an OPEN message from the

neighbor and is now waiting for either a KEEPALIVE or

NOTIFICATION message. When the device receives a KEEPALIVE

message from the neighbor, the state changes to Established.

When the message is a NOTIFICATION, the state changes to Idle.

• ESTABLISHED – BGP4 is ready to exchange UPDATE messages

with the neighbor.

• When there is more BGP data in the TCP receiver queue, a plus

sign (+) is also displayed.

Time The time that has passed since the state last changed.

Accepted The number of routes received from the neighbor that this device

installed in the BGP4 route table. Usually, this number is lower than the

RoutesRcvd number. The difference indicates that this device filtered

out some of the routes received in the UPDATE messages.

Filtered The routes or prefixes that have been filtered out.

Sent The number of BGP4 routes the device has sent to the neighbor.

ToSend The number of routes the device has queued to advertise and withdraw

to a neighbor.
