Need help - Maximum routes Sup 7E

[trung.nguyenxuan]

Hello everyone,

I'm using a Catalyst 4500 switch (C4507R+E) with Sup 7E. Cisco Datasheet of this switch says that it can learn maximum 256K IPV4 routes.

Currently it just learns 10330 ipv4 routes. However when I show platform hardware ip route summary, it seems that the FIB is just free 100K routes as below output:

Entity        total         used      free      util%                             

Entries       260096    10332      249764    3                                

  UC Ipv4     110592     10331     100261    9                                                                

  unused      147456    147456    0            100      

My question is: Can I make use of all 147456 unused routes? Or these ones have to use for any special purpose?

Thanks.

Hello community,

Please suggest me. Next week I plan to receive partial internet routes from my upstream, so I'd like to know the actual capacity of this 4500 switch.

Thanks.
