"Разрывается IPSec канал"  +/
Сообщение от rvv80 (ok) on 30-Июн-09, 21:44 
Ребята, знатоки Cisco, помогите, пожалуйста!
Периодически рвется канал IPSec между двумя Cisco-роутерами 2800 и 800 серий
Вот лог с включенным дебагом. Я понял только, что первая фаза проходит, что дальше?
BB.BB.BB.BB - ip-адрес циски с логами (800-серия)
AA.AA.AA.AA - ip-адрес другой циски (2800-серия)

1. "Разрывается IPSec канал"  +/

Судя по логу - это работа протокла DPD, причем штатная.
1. Покажите конфиги с обоих сторон
2. После обрыва - как долго восстанавливается канал? Что способстувует поднятию канала?
3. Пробовали мониторить доступность внешнего  интерфейса циски 800 с 2800? Т.е. есть 100% уверенность что косяк не провайдера?
4. посмотрите дебаг установки тунеля ipsec

После обрыва связи канал IPSec поднимается после перезагрузки циски. Провайдер - Корбина, мягко сказать предоставляет не очень стабильный канал (циска 800 стоит на складе, а там инет - радиорелейка). Во время падения IPSec-канала инет на складе есть (юзера по web-страничкам бегают), внешний интерфейс пингуется из офиса. Понятно, что для http стабильность канала менее важна, но все же...

Это единственный тунель или есть аналогичные 800е циски? Это к вопросу версии ИОСа, меняли/не меняли - помогло/нет?

Если ручками сбросить тунель с двух сторон после того как он отвалился (clear crypto...  ) связь восстанавливается?

И я бы попробовал сделать минимальный конфиг (без pfs, без spi-recovery, может бы снял бы с интерфейса IPS и Inspect)

Ну и смотреть еще раз дебаг ipsec без ike с двух сторон. и наборот.

800-ая серия не очень хорошо ведёт с шифрованием AES, лучше использовать 3des.
И вместо перезагрузки циски попробуйте клиронуть криптосессию, а потом запустить пинг с одного рутера на другой.
clear crypto session
ping BB.BB.BB.BB source AA.AA.AA.AA

Спасибо, большое за совет. Сейчас попробую, я и сам подумывал о смене типе шифрования, но только потому, что в рабочих конфигах с IPsec в инете везде используется 3des. А раз случались траблы у 800-й с AES, то теперь точно поробую.

Туннель один, прошивку меняли до меня. У цисок одинаковые прошивки Version 12.4(6)T
Разные только ROM: System Bootstrap, Version 12.3(8r)YI2 - у циски 800, Version 12.4(1r) [hqluong 1r] - у циски 2800

Делал clear crypto isakmp - не помогало, следующий раз попробую clear crypto session.
Без spi-recovery туннель валился намного чаще, IPS могу попробовать снять, а без Inspect придется увеличивать кол-во разрешающиих правил акцесс-листа файервола на вход... Как-то не хочется, это точно может повлиять на стабильность? Или 800-я настолько слабенькая, что Inspect может ее сильно грузить?
PFS точно попробую отключить, фиг с ней, с безопасностью...
Только вот возник вопрос: у какой SA должен быть больше lifetime у IKE или у IPSEC? Как вы ообычно настраиваете?
Кстати, вот повторяющиеся с момента обрыва IPSec куски лога с обоих роутеров (в конфиге пока ничего не менял, случилось после 2 недель непрерывной работы):
