Hi!
According to http://www.cisco.com/c/en/us/products/collateral/routers/asr-1000-series-aggregation-services-routers/data_sheet_c78-441072.html ASR1002-X supports "Up to 1,000,000 IPv4 or 1,000,000 IPv6 routes – 8GB Memory".
I think that this number of routes refers to the effective routes installed in RIB/FIB, am I right? The router I'm trying to size will have 3 full tables from three upstreams and 10k routes from OSPF so well over 1,5M total routes to compute between the two routing processes. The result is about 600k routes so it should fit.
Thanks!
