BGP NSF Configuration Example | Cisco Systems RSP8 guide

Enabling High Availability Features

BGP NSF Configuration 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

BGP NSF Neighbor Device Configuration 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

OSPF NSF Configuration Example

The following example configures OSPF NSF on a networking device:

Router# configure terminal

Router(config)# router ospf 400

Router(config-router)# nsf

IS-IS NSF Configuration Example

The following example configures Cisco proprietary IS-IS NSF operation on a networking device:

Router# configure terminal

Router(config)# router isis

Router(config-router)# nsf cisco

The following example configures IS-IS NSF for IETF operation on a networking device:

Router# configure terminal

Router(config)# router isis

Router(config-router)# nsf ietf
