I have recently look at the FIB TCAM usage on a 7600 receiving bgp full view for IPv4 & IPv6 traffic :
L3 Forwarding Resources
Module FIB TCAM usage: Total Used %Used
1 72 bits (IPv4, MPLS, EoM) 524288 441646 84%
144 bits (IP mcast, IPv6) 262144 11920 5%
detail: Protocol Used %Used
IPv4 439598 84%
MPLS 2048 1%
EoM 0 0%
IPv6 11913 5%
IPv4 mcast 4 1%
IPv6 mcast 3 1%
If IPv4 subnetting continues as it goes, it seems that we will reach the the 500k routes at the end of year 2013. So I have some questions :
Do you think that specifying 750k ipv4 routes (with mls cef command -- need a reload ?) and 125k ipv6 routes is a good limit that will always fit in the 5 upcoming years (or will this routeur be over / should I consider to split IPv6 & IPv4 peers on different routers) ?
How do you see ipv6 subnet number growing ? If most AS have only one IPv6 subnet it should be OK (around 50k AS) but if AS number continues to grow / some AS pick multiple prefix, it could be hard to manage with this platform
