Route vlans between 4507 & routers

i want to create a trunk between 4507 & 3945E router  & route two vlans from router 3945E

4507# vlan 99 & 51

       # int vlan 99

       # ip add 10.22.100.1/24

       #int vlan 51

       # ip add 10.22.103.1/24

      (config) #int g0/1

       (config-if)# I do not see "switchport trunk encapsulation dot1Q" on 4507

3945#int g0/0

       #int g0/0.51

       #encapsulation do1q

       #ip add 10.22.103.2/24

       #int g0/0.99

       #encapsulation dot1q

       #ip add 10

4507 version :

IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSAL-M), Version 03.02.00.SG RELEASE SOFTWARE (fc4)

3945E: 15.1(2)T4

Re: Route vlans between 4507 & routers

Hi,

I think this iwhat you want.

The 3945 will be a intervlan router for VLANs 51 & 99

### 4507 ###

!
int g1/48
description **** TRUNK TO 3945E ****
switchport trunk allowed vlan 51,99
switchport mode trunk
!

### 3945E ###

!
!
int g0/0
desc *** TRUNK to 4507 ***
!
int g0/0.51
encapsulation dot1Q 51
ip address 10.22.103.1 255.255.255.0
!
int g0/0.99
encapsulation dot1Q 99
ip address 10.22.100.1 255.255.255.0
!
