Abstract

Official abstract text for this publication.

In general, techniques are described for selectively invoking graceful restart procedures when a route reflector member of a redundant route cluster fails. In one example, a method is provided that includes determining, by a provider edge router that supports graceful restart procedures, that a first router forms a redundant group with at least a second router. The method also includes detecting a failure of the first router and determining that at least the second router in the redundant group is operating approximately while the first router is failed. The method further includes overriding graceful restart procedures with respect to the failed first router when at least the second router is operating. The method also includes forwarding one or more data packets according to route information provided via the second router.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method, comprising: determining, by a provider edge router that supports graceful restart procedures, that a first route reflector that advertises a set of routes forms a redundant group with at least a second route reflector that advertises the set of routes; receiving, by the provider edge router from the first route reflector, a first copy of the set of routes and forwarding data packets according to the first copy of the set of routes; receiv…
