Hi, What is the meaning of Graceful restart , how we can implement this in OSPF , BGP & Eigrp ?
12-30-2008 09:57 PM
From a Network World article:
Using BGP graceful restart, the data-forwarding plane of a router can continue to process and forward packets even if the control plane - which is responsible for determining best paths - fails.
Graceful restart also reduces routing flaps, which stabilizes the network and reduces the consumption of control-plane resources.

Graceful Restart (GR) is a way to rebuild forwarding information in routing protocols when the control plane has recovered from a failure.
EIGRP
router eigrp 100
eigrp nsf
OSPF
Router(config)# router ospf 4
Router(config-router)# nsf cisco/ietf
BGP
switch(config)# router bgp 65536
switch(config-router)# graceful-restart
