IPv6 Link Local Addresses

The Oracle® Enterprise Session Border Controller supports IPv6 Link Local addresses configured for a network interface’s gateway.

An IPv6 link local address is signified by its first hextet set to FE80:. Even if a network interface’s first hextet is not FE80, but the gateway is, the Oracle® Enterprise Session Border Controller will still function as expected.

show neighbor-table

The show neighbor-table command displays the IPv6 neighbor table and validates that there is an entry for the link local address, and the gateway uses that MAC address.
