Configuring IP Routing over TRISL

The IP routing over TRISL VLANs feature extends IP routing capabilities to include support for routing IP frame types in VLAN configurations. To configure IP routing over TRISL, use the following commands beginning in global configuration mode:

	Command	Purpose
Step 1
	Router(config)# ip routing	Enables IP routing on the router.
Step 2
	Router(config)# interface type	Specifies the subinterface on which TRISL will be used.
	slot/port.subinterface-number
Step 3
	Router(config-if)# encapsulation	Defines the encapsulation format, and specifies the VLAN identifier.
	tr-isl trbrf-vlan vlanid bridge-num
	bridge-number
Step 4
	Router(config-if)# ip address	Sets a primary IP address for an interface.
	ip-address mask
