Multinetting (Ip Subinterfaces) Configuration; Vlan Tagging And Forwarding Over Ethernet Summary - Avaya 1000 Series Configuration Manual

Multinetting (IP Subinterfaces) Configuration

Another variation for multiple subnet support that does not involve VLAN Tagging is IP Multi-
Net.
interface ethernet 0
ip address 47.17.187.15 255.255.255.0
exit ethernet
interface ethernet 0.1
ip address 192.168.44.44 255.255.255.0
exit ethernet
Note:
The Ethernet subinterface shares the same broadcast domain as the primary interface
Note:
Each subinterface is assigned a unique Source MAC address. The final octet of the MAC
address encodes the internal unit number.
Note:
The Ethernet interface is placed into Promiscuous mode. It will receive all packets on the
interface including non-broadcast packets that are not addressed to the router. This can
result in higher workload on the router.

VLAN Tagging and Forwarding over Ethernet Summary

• To support a single untagged bridged VLAN on the Ethernet
- do not specify any encapsulation on the Ethernet
- add a dummy IP address on the interface
- configure the vlan and vlanid on the Ethernet
- do not add the ethernet interface to the vlanfwd list
• To support multiple tagged bridged VLANs on the Ethernet
- do not specify any encapsulation on the Ethernet
- add a dummy IP address on the interface
- do not configure the vlan and vlanid on the Ethernet
- add each ethernet interface / tag to the vlanfwd list
