Configuring IP InterVLAN Routing on the RSM

(2012-09-06 07:18:42)

Step 1 (Optional) Enable IP routing on the router1.
  ip routing
  
  Step 2 (Optional) Specify an IP routing protocol2.
  router ip_routing_protocol
  
  Step 3 Specify a VLAN interface on the RSM.
  interface vlan-id
  
  Step 4 Assign an IP address to the VLAN.
  ip address n.n.n.n mask
  
  Step 5 Exit configuration mode.
  Ctrl-Z
  This example shows how to enable IP routing on the RSM, create a VLAN interface, and assign the interface an IP address:
  
  Router#configure terminal
  
  Enter configuration commands, one per line. End with CNTL/Z.
  Router(config)#ip routing
  
  Router(config)#router rip
  
  Router(config-router)#network 10.0.0.0
  
  Router(config-router)#interface vlan 100
  
  Router(config-if)#ip address 10.1.1.1 255.0.0.0
  
  Router(config-if)#^Z
  
  Router#
  
  Configuring IP InterVLAN Routing on an External Ro
  Step 1 (Optional) Enable IP routing on the router1.
  ip routing
  
  Step 2 (Optional) Specify an IP routing protocol2.
  router ip_routing_protocol
  
  Step 3 Create a subinterface on a physical interface.
  interface interface_type interface_number.subinterface-_number
  
  Step 4 Specify the encapsulation and VLAN number to use on the subinterface.
  encapsulation encapsulation_type vlan_id
  
  Step 5 Assign an IP address to the subinterface.
  ip address n.n.n.n mask
  
  Step 6 Repeat Steps 3-5 for each VLAN between which you want to route traffic.
  
  
  Step 7 Exit configuration mode.
  Ctrl-Z
  
  This example shows how to enable IP routing on the router, create two subinterfaces, and specify the encapsulation, VLAN number, and IP address for each subinterface:
  
  Cisco7505#configure terminal
  
  Enter configuration commands, one per line. End with CNTL/Z.
  Cisco7505(config)#ip routing
  
  Cisco7505(config)#router rip
  
  Cisco7505(config-router)#network 10.0.0.0
  
  Cisco7505(config-router)#interface fastethernet2/0.100
  
  Cisco7505(config-subif)#encapsulation isl 100
  
  Cisco7505(config-subif)#ip address 10.10.1.1 255.255.0.0
  
  Cisco7505(config-router)#interface fastethernet2/0.200
  
  Cisco7505(config-subif)#encapsulation isl 200
  
  Cisco7505(config-subif)#ip address 10.20.1.1 255.255.0.0
  
  Cisco7505(config-subif)#^Z
  
  Cisco7505#
