[Xorp-users] Xorp and ospf memory usage?

[Atanu Ghosh]

Hi,

This memory usage seems too high, could you send me the LSA database
so that I can try this for myself?

The program print_lsas with the '-S' argument will save the LSA database
to a file, you will find the program in the tools directory under ospf.

    Kimmo> This 60-70 Mb sounds quite much, comparing to the study made

    Kimmo> In that study, quagga, nexthop gated, ipinfusion zebos and

    Kimmo> So, my question is, how much xorp should consume memory when
