Symptom: Unable to block multicast traffic from entering into EOIP Conditions: CSCtr26626 requests support for multicast traffic on anchored wlan, but muticast mdns traffic does travel through EOIP tunnel and seem to egress out of DMZ WLC port. Customer on (WLC 18.104.22.168) where he doesn't want the guest users mdns traffic 22.214.171.124 to reach his DMZ WLC via EOIP. MDNS profile is also disabled on wlan, corresponding interfaces on both on anchor and foreign but mdns traffic still shows up on DMZ WLC and egresses out to its interface. ACL on foreign and DMZ per recommendations on http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_tech_note09186a0080bb1d7c.shtml#block blocks some but not all mdns traffic. Need ability to stop multicast/mdns traffic from traversing through EOIP tunnel or fix WLC ACL on DMZ to block all MDNS traffic coming via EOIP.
