BigIron RX(config)# vlan 2
BigIron RX(config-vlan-2)# tagged e 1/1 to 1/2
BigIron RX(config-vlan-2)# router-interface ve 2
BigIron RX(config-vlan-2)# exit
BigIron RX(config)# interface ve 2

Syntax: router-interface ve <ve-number>
Enter 1 to the maximum number of virtual routing interfaces supported on the device for
<ve-number>.

Bridging and routing the same protocol simultaneously on the same

device

Some configurations may require simultaneous switching and routing of the same single protocol
across different sets of ports on the same router. When IP routing is enabled on a device, you can
route IP packets on specific interfaces while bridging them on other interfaces. In this scenario, you
can create two separate backbones for the same protocol, one bridged and one routed.
The following is a sample configuration for the illustration above.
BigIron RX(config)# vlan 2
BigIron RX(config-vlan-2)# tagged e 1/1 to 1/2
BigIron RX(config-vlan-2)# router-inter ve 2
BigIron RX(config-vlan-2)# ip-proto static e 1/1/ to 1/2
BigIron RX(config-vlan-2)# exit
BigIron RX(config)# vlan 3
BigIron RX(config-vlan-3)# tagged e 1/13 to 1/24
BigIron RX(config-vlan-3)# router-int ve 3
BigIron RX(config-vlan-3)# exit
BigIron RX(config)# interface ve 2
BigIron RX(config-ve-2)# ip address 10.1.1.1/24
BigIron RX(config-if-e1000-2/1)# exit
BigIron RX(config)# interface ve 3
BigIron RX(config-ve-3)# ip address 11.1.1.2/24
IP packets are bridged (switched) within the same protocol VLAN if they are on the same subnet;
they are routed if they are on a different VLAN.
