DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Example This example shows how to enable the security of the BGP network for autonomous system 65534. All incoming updates from eBGP peers are examined to ensure that the first AS number in the AS-path is the local AS number of the transmitting peer: Switch# configure terminal Switch(config)# router bgp 65534 Switch(config-router)# bgp enforce-first-as Switch(config-router)# 13-22 bgp fast-external-failover (MI and EI Mode Only) This command is used to immediately reset an external BGP peering session if the link directly connected to the peer goes down. Use the no form of this command to disable BGP fast external failover. bgp fast-external-failover no bgp fast-external-failover Parameters None. Default By default, this option is enabled. Command Mode Router Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to globally disable or enable fast external failover of BGP sessions for the directly connected external peers. When this command is enabled, the session is immediately reset if the link goes down. When this command is disabled, the session will not be reset until the default hold timer expires (3 keep alive times). Example This example shows how to configure the BGP fast external failover feature as disabled. If the link through which the session is carried flaps, the session will not be reset. Switch# configure terminal Switch(config)# router bgp 65534 Switch(config-router)# no bgp fast-external-failover Switch(config-router)# 13-23 bgp graceful-restart (MI and EI Mode Only) This command is used to enable the BGP graceful restart capabilities for all BGP neighbors. Use the no form of this command to revert to the default setting. 193
