Re: Graceful Restart

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.

Re: Graceful Restart

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

Pls rate the post if it was helpful.
