Peter, When PE report the route as Type3 LSA to CE (redistributed, might be huge in number), In this scenario is there a good mechanism to aggregate Type3 LSAs at PE before sending to CE.
For such kind of Type3 Aggregation should we use backbone area range since PE router is considered as integral part of OSPF backbone?

Keshava, it's up to the implementation how it handles the aggregation of the BGP redistributed prefixes on PE. The most obvious choice is to treat it the same way as regular redistribution in which case an external LSA is generated for the summary itself. RFC4577 only specifies the behavior when no aggregation is done on PE: In the following, we specify what is reported, in OSPF LSAs, by the PE to the CE, assuming that the PE is not configured to do any further summarization or filtering of the routing information before reporting it to the CE." thanks, Peter On 16.11.2010 11:33, Keshava.Ayanur wrote: > Hi, > > Any thoughts about aggregating the "Summary LSA's' originated in PE > which was redistributed from BGP . > > Regards, > > Keshava.A.K. > > > > _______________________________________________ > OSPF mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/ospf _______________________________________________ OSPF mailing list [email protected] https://www.ietf.org/mailman/listinfo/ospf _______________________________________________ OSPF mailing list [email protected] https://www.ietf.org/mailman/listinfo/ospf
