Да, да, не надо надо мной смеяться и показывать пальцем. :) Да, DS3. :P
Load-test 7200/VXR NPE400 показал, что её можно нагрузить 100М+100M, при
среднем размере пакета в 380 байт она вполне держит, нагрузка на проц в
среднем 93%, пакеты не роняет, от количества EoMPLS туннелей ангрузка не
зависит.
А, эта. На версии IOS 12.3T нагрузка проца существенно ниже. При 100М+100М и
размере пакетов в 380 байт 12.3Т грузил проц на 84-85%.
Вот кусок моего репорта:
(Для справки, два рутера в тесте были соединены через 100M Ether, ГигЕ на
вход и выход).

This is a current state of affairs (no ATM yet, 21 VLAN provisioned between
Mel and Syd for load testing). Results of a day's worth load test are:
Pushing 21 VLAN with 4M on each worth of 380-byte packets. Offered rate:
79Mbps (excl. L2TPv3 encapsulation), transit rate (incl. L2TPv3) - 87Mbps.
12.3(2)T1 cpu usage:
Syd>sh proc cpu
CPU utilization for five seconds: 84%/84%; one minute: 85%; five minutes:
85%
12.0(26)S cpu usage:
Mel>sh proc cpu
CPU utilization for five seconds: 93%/93%; one minute: 92%; five minutes:
