KorDen Posted December 20, 2016 Share Posted December 20, 2016 (edited) Вот опять удалось повторить то, что было с самого появления IPIP-туннелей Имеем: Ultra 2 (v2.08(AAUX.2)A12) - "сервер", Giga 2 на аналогичной прошивке - "клиент". Запускаем обновление Ultra 2 на .3, после обновления и перезагрузки ждем час, гигу 2 не трогаем.. А туннель все не поднимается... Скрытый текст Гига (config)> show interface IPIP0 id: IPIP0 index: 0 type: IPIP description: interface-name: IPIP0 link: up connected: yes state: up mtu: 1420 tx-queue: 0 address: 192.168.100.2 mask: 255.255.255.0 uptime: 61961 global: no security-level: private Ультра (config)> sh interface IPIP0 id: IPIP0 index: 0 type: IPIP description: interface-name: IPIP0 link: up connected: yes state: up mtu: 65516 tx-queue: 0 address: 192.168.100.1 mask: 255.255.255.0 uptime: 4386 global: no security-level: private Замечаем явно абсурдный MTU на ультре, перевключаем туннель на гиге, и все начинает работать Скрытый текст (config)> interface IPIP0 down Network::Interface::Base: "IPIP0": interface is down. (config)> show interface IPIP0 id: IPIP0 index: 0 type: IPIP description: interface-name: IPIP0 link: down connected: no state: down mtu: 1420 tx-queue: 0 global: no security-level: private (config)> interface IPIP0 up Network::Interface::Base: "IPIP0": interface is up.
