Здравствуйте.
Облазил весь интернет, но похоже, что с данной проблемой столкнулся я один.
Решил настроить на CISCO 881W мультикаст для просмотра IPTV.
Разрешил роутинг командой ip multicast-routing, но настроить интерфейсы не могу, т.к. команды ip pim нет ни на одном интерфейсе. Команд типа show ip pim тоже нет.

WMrouter#show ip multicast
  Multicast Routing: enabled
  Multicast Multipath: disabled
  Multicast Route limit: No limit
  Multicast Fallback group mode: Sparse
  Number of multicast boundaries configured with filter-autorp option: 0

WMrouter(config)#interface vlan 1
WMrouter(config-if)#ip pim ?
