DMVPN Cisco (HUB) + Cisco (Spoke_1) + ESR 100 (Spoke_2)
Добавлено: 16 мар 2022 21:26
Добрый день.
DMVPN, IPSec'а - нет.
Проблемы:
1. HUB - SPOKE_2 (ELTEX) не поднимается OSPF, пинг есть между ними (между другим SPOKE_1 и HUB - eigrp работает, OSPF не нужен) -
2. Нет пинга SPOKE-SPOKE (вернее ИНОГДА проскакивает ОДИН пакет ICMP, остальные - тайм аут)
Помогите пожалуйста, глаз "замылился", не могу понять в чём проблема.
И ещё - почему на Элтекс нет параметра - ip nhrp network-id [Значение] и HUB-SPOKE поднялся, а на Cisco без указания ip nhrp network-id [Значение] - тунель не поднимается?
