If bridgeIfAddressType is set to unicast_mac(1), then bridgeIfMacOrIpAddress represents a MAC Address, and ifIndex, bridgeIfVlanId and bridgeIfMacOrIpAddress are used for the bridge path. If bridgeIfAddressType is set to multicast_mac(2), then bridgeMacOrIpAddress represents a MAC Address, and ifIndex, bridgeIfVlanId and bridgeIfMacOrIpAddress are used for the bridge path. If bridgeIfAddressType is set to ip_address(3), then ifIndex and bridgeIfVlanId are used for the bridge path. If bridgeIfAddressType is set to dhcp_mac(4), or dhcp_ip(5), then the address is as desribed for types 1 and 3, respectively, and the address was learned by snooping DHCP packets. ipV6Address(6) is the same as ipAddress(3) except for IPv6 address format. dhcpV6Mac(7) is the same as dhacpMac(4) except for IPv6 address format. dhcpV7Ip(8) is the same as dhcpIp(5) except for IPv6 address format.
