Those routes are stored in the 8MB SSRAM on your FEB but also a copy of this table is stored in the DRAM, 64MB in your case. You reached the limits of your DRAM, not the SSRAM. Upgrading it should help, either by buying a newer router like M7i/M10i(with 256MB DRAM on the FEB) or by installing a enhanced FEB for M10 routers. > Does this mean those of us stuck on 64MB FEB/SSB systems are going to > have to run without RPF now or in the very near future when the size > of a full table grows a bit more? Pretty much, yes. 64MB isn't simply large enough for todays full-table + arp entries + RPF + ... 128MB or more might be sufficient for that. We reached our limits on a M20 router with SSB-E with about 7500 arp entries, full-table and no RPF. Upgrading to SSB-E16 solved that problem.
