[c-nsp] SUP720's memory, looking at options..

I am guessing with the RSP720 (vs the SUP720), you don’t have to worry about memory running out as quickly.  Sure the TCAM will exhaust at some point, but at least you can upgrade the RAM to 4G if needed.

 

Has anybody come up with a good guess as to what is a good division of the TCAM for BGP routing?    I have had mine at 640K for IPv4 for a while, but looking at the v4 to v6 ratios, I am thinking maybe 768 for v4 may be a better guess..

Thanks, 

I plan on upgrading to SRE12 as well as repartioning the TCAM for now.

Not that I am aware of, as I mentioned earlier, my SUP720-3BXL's are
currently at 92% memory used, and I haven't had any problems at all with
them to date.   Looking at jumping to RSP720's or some platform with more
memory to stop future issues, but have never had problems sshing into the
boxes..
