I've got a 2811 running 12.4(8) and a 2950 running (C2950-I6K2L2Q4-M), Version 12.1(22)EA8a.
i have been tinkering trying to get the 2811 connect to a cable modem, setting it up as a VTP server, and connecting the 2950 to it to access the VLAN's defined on the 2811.
does anyone have an example config for this type of configuration? dont have anything specific requirements, and just looking to learn and find out if its possible.
you can use the C2811 as router for intervlan routing with no problems
C2950: vtp server or transparent you create here the required vlans example: 10,20,30
you configure a L2 trunk port to router port with
switchport mode trunk
no ip address
enc dot1q 10
ip address 10.10.10.1 255.255.255.0
enc dot1q 20
ip address 10.10.20.1 255.255.255.0
enc dot1q 30
ip address 10.10.30.1 255.255.255.0
this is what you need and the C2811 will perform intervlan routing for users in the different vlans
Hope to help
