Required knowledge:
First, we should understand Catalsty 4908G-L3. In fact, it is a vro that uses the cisco ios configuration interface completely. By default, all interfaces are routable interfaces. Catalsty 4908G-L3 does not support L2 protocol, VLAN trunk protocol, dynamic trunk protocol, and port aggregation protocol.

Catalsty 4908 does not support the following types: IOS 12.07-based
1. Access Control List.
2 802.1q
3 apple talk routing
4 port snooping
Catalsty 4908 swtich-router running Cisco IOS 12.0 (7) W5 (15D)
Three Catalsty 3512xl switch running cisco iso 12.0 (5) xu
Configure the Catalsty 4908 switch for two purposes.
Run five VLANs 1 10 20 30 40 on a L2 Switch.
Communication between different VLANs
Two Catalsty 3512xl switches are connected to 4908G-L3 using a gibit Ethernet link, and the other one is connected using a single gibit link.
To support internal VLAN routing, integrated routing and bridging. All end users and servers are connected to Catalsty 3512XL. If a device in a VLAN wants to connect to a device in another VLAN, the data will be sent to 4908G-L3, it routes data to a virtual bridge interface.
The following configuration should be applied to the vswitch:
Basic start-up configuration
The IP address and the default gateway should be allocated to the vswitch for management.
The VTP mode should be set to transparent mode, so that VLAN can be configured on the 3512XL switch.
The gibit Ethernet channels are on the 4908G-L3 and 3512XL01 3512XL02
The route of the bridge and Virtual Interface, IP address and IPX should be configured on 4908
Isl trunks should be configured on 4908G-L3 and 3512XL bridging should be configured on the TRUNK Sub-interface
Vlan IP subnet IPX NETWORK
1 10.10.1.0/24 N/
10 10.10.10.0/24 1000
20 10.10.20.0/24 2000
30 10.10.30.0/24 3000
4000 10.10.40.0/24
On Catalsty3512xl, configure an IP address and the default gateway to manage the switch. The default gateway address is the address of the bridge Virtual Interface on Catalsty 4908G-L3.

Configure CAT4908 to use the bridging and routing functions. For inter-VLAN routing, use bridge ibr to start the routing and bridging functions. ISL is configured between switches. The VLAN sub-interfaces are added to the corresponding bridging group to create a separate layer-2 domain in the isl trunk.

Ipx routing starts IPX routing on 4908G-L3
Bridge IBR is integrated with the routing and bridging functions. And allow communication in the bridge group.
Bridge number protocol ieee creates a spanning tree that runs on the IEEE protocol with the bridging function.
Configure isl trunk on the vswitch
To configure isl trunk on Catalsty 4908G-L3, you must configure sub-interfaces under the master interface. Each sub-interface transmits data to each other in each VLAN, and the two trunks are configured on the logical PORT-CHANNEL interface, the third TRUNK is configured on the physical interface.
