Configuring virtual routing interfaces
11
The device can locally route IP packets between VLANs that are defined within a single router. All
other routable protocols or protocol-based VLANs (for example, IPX and AppleTalk) must be routed
by another external router capable of routing the protocol.
If you do not need to further partition the port-based VLAN into protocol-based VLANs, you can
define a single virtual routing interface at the port-based VLAN level and enable routing on a single
virtual routing interface.
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
BigIron RX(config-ve-2)# ip address 10.1.1.1/24
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 ethernet 1/1 to 1/2
BigIron RX(config-vlan-2)# router-interface ve 2
BigIron RX(config-vlan-2)# ip-proto
BigIron RX(config-vlan-group-ip-proto)# static ethernet 1/1/ to 1/2
BigIron RX(config-vlan-group-ip-proto)# exit
BigIron RX(config-vlan-2)# exit
BigIron RX(config)# vlan 3
BigIron RX(config-vlan-3)# tagged ethernet 1/13 to 1/24
BigIron RX(config-vlan-3)# router-interface ve 3
