using vrfs with eigrp

Hi Everyone


I need to get two vrfs configured on some 3750 switches. I started off by configuring one vrf on three switches, A connected to B and B connected to C. The config was very simple like below but it didnt work:


switch a example:


ip vrf admin

rd 100:1

route-target import 100:1

route target export 100:1


interface gigabitethernet 1/0/24

ip vrf forwarding admin

ip address


router eigrp 100



The rest of the config for switches B and C were configured the same. I could ping the next hop but I couldnt ping from switch A to C.


Now I found another guide on the internet and it had additional configuration that I needed to add to eigrp. So I configured:


router eigrp 100

address-family ipv4 vrf admin

network 0.0.03


Now i tried to add the command:

autonomous-system 100

However my switch wont accept this command even though the switch gives me a warning that i need to configure an autonomous system number.


My question is,am i on the right path here? and also why isnt my switch taking this command? the switch ios is 15 and its a universalk9.


Thanks for your help
