Tassos, Surely with this TCAM space, there are lots of routes which can be supported:
http://www.cisco.com/en/US/docs/wireless/asr_900/hardware/installation/overview.html Supported RSPs: The Cisco ASR 903 Series Aggregation Services Router supports the following RSPs: •A900-RSP1A-55—Provides 2 GB of SDRAM, 5 Mb of TCAM memory, 3-Mb buffer table, 576-Mb forwarding memory, and 1,536-Mb packet buffer memory. •A900-RSP1B-55—Provides 4 GB of SDRAM, 20 Mb of TCAM memory, 144-Mb buffer table, 1152-Mb forwarding memory, and 1,536-Mb packet buffer memory. vs the ASR 1000 Series: http://www.cisco.com/en/US/prod/collateral/routers/ps9343/data_sheet_c78-450070_ps2797_Products_Data_Sheet.html For 2.5-Gbps/5-Gbps integrated ESP in ASR1001: 256MB Cisco QuantumFlow Processor, 1GB DRAM, 5Mb ternary content addressable memory (TCAM), and 64MB packet buffer memory For 5-Gbps Cisco ASR 1000 ESP: 256MB Cisco QuantumFlow Processor, 512MB DRAM, 5Mb ternary content addressable memory (TCAM), and 64MB packet buffer memory For 10-Gbps Cisco ASR 1000 ESP: 512MB Cisco QuantumFlow Processor, 2GB DRAM, 10Mb TCAM, and 128MB packet buffer memory For 10-N-Gbps Cisco ASR 1000 ESP: 512MB Cisco QuantumFlow Processor, 2GB DRAM, 10Mb TCAM, and 128MB packet buffer memory For 20-Gbps Cisco ASR 1000 ESP: 1GB Cisco QuantumFlow Processor, 4GB DRAM, 40Mb TCAM, and 256MB packet buffer memory Rolf On 23 Mar 2012, at 10:30 AM, Tassos Chatzithomaoglou wrote: > ASR903 seem more like a modular ME-3800X, with the ability to upgrade the RSP > if needed. > > -- > Tassos > > Rolf Mendelsohn wrote on 23/3/2012 11:00: >> Waris, >> >> How many routes does the ASR903 support? >> >> Rolf >> >> On 23 Mar 2012, at 8:45 AM, Waris Sagheer (waris) wrote: >>> ASR 903 runs IOS XE and ASR901 runs classical IOS. >>> ASR 901 Scale: >>> IPv4 Routes - 12K >>> BGP peers - 100 >>> Number of VRF - 128 >>> IPv6 support is in roadmap for August timeframe. >>> >>> ASR 903 is capable of line rate performance.
