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:

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
