Configuring Layer 3 Interfaces
For the Hybrid Switch Router, it is important to understand that by default, all interfaces in OcNOS are L3 ports. If a port has been configured as L2, then use the no switchport command to make it a L3 port.
For example:
#configure terminal | Enter the Configure mode. |
(config)#interface eth3 | Specify an interface to configure and enter the Interface mode. |
(config-if)#no switchport | Configure eth3 as a Layer 3 port. |
(config-if)#commit | Commit the candidate configuration to the running configuration |
(config-if)#exit | Exit interface mode |
In the Hybrid Switch Router mode, if a VLAN is configured, a Layer 3 interface based on the bridge-group number and VLAN ID is created. This Layer 3 interface is advertised to all the Layer 3 protocols. For example:
#configure terminal | Enter the Configure mode. |
(config)#bridge 1 protocol mstp | Creating bridge. |
(config)#vlan database | Enter the VLAN configure mode. |
(config-vlan)#vlan 2 bridge 1 | Enable VLAN 2 on bridge 1. |
(config-vlan)#commit | Commit the candidate configuration to the running configuration |
(config-vlan)#exit | Exit VLAN configure mode |
The last step in the example above show an interface given a name with the following format:
vlanXX.YYYY
Where XX is the bridge ID, and YYYY is the VLAN ID,
For example, the name, vlan1.3 indicates that VLAN IP’s interface is in VLAN 3, and bridge-group 1.
