The data sheets for the 1800 series all mention hardware-based
encryption being built into the units. The 1841 mentions AIM support as
well for "two to three times the performance of embedded encryption
capabilities." No mention of AIM support for the 1861 but it too says
hardware-based encryption. Does anyone have any performance numbers for
IPSec-encrypted GRE on the 1800 series or the 800 series? I'm looking
for an inexpensive platform for originating IPSec-encrypted GRE tunnels.
Throughput will be reasonably low. OSPF and EIGRP support is
required. It looks like the most cost-effective solution is the 881
with the Adv IP code which replaces the 871 (same price). The 1811,
1841 and 1861 all require DRAM and flash upgrades to support their
respective image that has IPSec and IGP support (Adv IP for the 1811 and
Adv Sec for the 1841 and 1861). That seriously jacks up the price
compared to the turnkey 881. Any other recommendations?
