Задача очень простая, на одном vlan-е есть Multicast-Server (Vlan 10) вещает на 224.224.224.224, а на другом нужно смотреть мультикаст-трафик (Vlan 20).
Вроде все как по доке делаю, а ничего не работает.

Прежде чем обратиться с вопросом читал:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_configuration_guide_chapter09186a00800d6b79.html

может я что-то не так понял?
