Configuring Bgp Nsf Example; Configuring Bgp Nsf Neighbor Device Example; Configuring Ospf Nsf Example - Cisco RSP2 - Route Switch Processor 2 Installation And Configuration Manual

Command
Router# show isis database [detail]
Router# show isis nsf
The following tips may help you to troubleshoot the device.
The system displays FIB errors.
Use the show cef state command to verify that distributed CEF switching is enabled on your platform.
To enable distributed CEF, enter the ip cef distributed command in global configuration mode on the
active RSP.
Cannot determine if an OSPF neighbor is NSF-aware.
To verify whether an OSPF neighbor device is NSF-aware and if NSF is operating between them, use
the show ip ospf neighbor detail command.
The system loses, or appears to lose, adjacencies with network peers following a stateful
switchover.
Use the show clns neighbors detail command to find any neighbors that do not have "NSF capable" and
make sure that they are running NSF-aware images.
Additionally, for ISIS, the standby RSP must be stable for 5 minutes (default) before another restart can
be initiated. Use the nsf interval command to reset the restart period.

Configuring BGP NSF Example

The following example configures BGP NSF on a networking device:
router# configure terminal
router(config)# router bgp 590
router(config-router)# bgp graceful-restart

Configuring BGP NSF Neighbor Device Example

The following example configures BGP NSF on a neighbor router. All devices supporting BGP NSF
must be NSF-aware, meaning that these devices recognize and advertise graceful restart capability.
router# configure terminal
router(config)# router bgp 770
router(config-router)# bgp graceful-restart

Configuring OSPF NSF Example

The following example configures OSPF NSF on a networking device:
router# configure terminal
router(config)# router ospf 400
router(config-router)# nsf
OL-4923-01 B0
Purpose
Displays the IS-IS link-state database.
Displays the current state information regarding IS-IS Cisco NSF.
