Мне не удалось найти никакой документации или примеров, где / 30 использовался для настройки интерфейса VRRP на маршрутизаторе cisco. Возможно ли это, если у кого-нибудь есть пример?
interface GigabitEthernet0/0.1507
description CUSTOMER WAN
encapsulation dot1Q 1507
ip address X.X.X.X 255.255.255.252 // I don't have an extra IP
vrrp 150 address 10.102.32.210
vrrp 150 description VLAN 1507

Я понимаю, что это правильный синтаксис, но, очевидно, когда мне нужно использовать / 30 WAN, у меня нет дополнительного IP-адреса для интерфейс резервного роутера.
