When the Firewall Works in Transparent Mode, OSPF Neighbor Relationships Cannot be Established

Publication Date:  2012-07-17 Views:  264 Downloads:  0
Issue Description
When the firewall works in transparent mode, OSPF neighbor relationships cannot be established.
Alarm Information
None.
Handling Process
In the system view, run the following command:
[USG5300]firewall unknown-mac multicast flood     //for transparent transmission of multicast packets
Root Cause
When the firewall works in transparent mode, it does not allow multicast packets through by default. OSPF packets are multicast packets, so request packets for establishing neighbor relationships are not allowed through the firewall. As a result, neighbor relationships cannot be established.
Suggestions
None.
