Не поднмиается автоматически туннель IPIPoverIPsec после перезагрузки "сервера"


Recommended Posts

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...

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

Network::Interface::Base: "IPIP0": interface is down.
(config)> show interface IPIP0

               id: IPIP0
            index: 0
             type: IPIP

(config)> interface IPIP0 up
Network::Interface::Base: "IPIP0": interface is up.
(config)> show interface IPIP0

               id: IPIP0
            index: 0
             type: IPIP
      description:

        connected: yes

         tx-queue: 0
          address: 192.168.100.2
             mask: 255.255.255.0
           uptime: 4

На ультре сразу нормализуется MTU


(config)> sh interface IPIP0

               id: IPIP0
            index: 0
             type: IPIP
      description:
   interface-name: IPIP0
             link: up
        connected: yes
            state: up
              mtu: 1420
         tx-queue: 0
          address: 192.168.100.1
             mask: 255.255.255.0
           uptime: 4665
           global: no
   security-level: private
