All rights reserved. 4 BGP Scaling Techniques • How does a service provider: Scale the iBGP mesh beyond a few peers? Implement new policy without causing flaps and route churning? Keep the network stable, scalable, as well as simple? • Three Techniques: Route Refresh, Flap Damping, Route Reflector APRICOT2005 ©2005, Cisco Systems, Inc.

All rights reserved. 6 Route Refresh Problem: • Hard BGP peer reset required after every policy change because the router does not store prefixes that are rejected by policy • Hard BGP peer reset: Tears down BGP peering Consumes CPU Severely disrupts connectivity for all networks Solution: • Route Refresh APRICOT2005 ©2005, Cisco Systems, Inc. All rights reserved. 777 Route Refresh Capability • Facilitates non-disruptive policy changes • For most implementations, no configuration is needed Automatically negotiated at peer establishment • No additional memory is used • Requires peering routers to support “route refresh capability” – RFC2918 APRICOT2005 ©2005, Cisco Systems, Inc. All rights reserved. 888 Dynamic Reconfiguration • Use Route Refresh capability if supported find out from the BGP neighbour status display Non-disruptive, “Good For the Internet” • If not supported, see if implementation has a workaround • Only hard-reset a BGP peering as a last resort Consider the impact to be equivalent to a router reboot APRICOT2005 ©2005, Cisco Systems, Inc.
