An engineer is configuring multicast for two WLCs. The controllers are in different physical locations and each handles around 500 wireless clients. How should the CAPWAP multicast group address be as

The correct answer is A. Each WLC must be assigned a unique multicast group address. Choose Controller > General to configure AP multicast mode (multicast or unicast) & CAPWAP multicast group address(only for multicast mode). Use private multicast IP (239.0.0.0/8) for the group address, but avoid 239.0.0.x or 239.128.0.x as these overlap with the link local MAC a

Explanation

Choose Controller > General to configure AP multicast mode (multicast or unicast) & CAPWAP multicast group address(only for multicast mode). Use private multicast IP (239.0.0.0/8) for the group address, but avoid 239.0.0.x or 239.128.0.x as these overlap with the link local MAC addresses & flood out all switch ports. This group address cannot be used for any application in your network. If you have multiple controllers, configure different group address for different https://mrncciew.com/2012/11/17/configuring-multicast-on-wlc/
