Hi Guys,
I've taken over a network and have the following issue that I would like your advice on. I need to add a new POE switch with a new Voice Vlan to the existing EIGRP network. The problem is that we have a router which I do no have access to (great things about inherited networks). The network topology is as described:
New 3750 -- Layer 2 2950 -- 2811 Router
The 2811 Router has EIGRP configured:
router eigrp 200
no auto-summary
no eigrp log-neighbor-changes
network 10.1.1.0
network 10.1.2.0
network 10.1.3.0
The router's fa0/0 interface is connected to the 2950 switch on the 10.1.1.0 network.
My plan is that since I cannot access the 2811 router, I will add the 3750 as a Layer 3 device that will share the new voice Vlan 10.1.100.0.
What I did was create Vlan interfaces on the 3750 for both the 10.1.1.0 network and the 10.1.100.0 network.
I then created a dot1q trunk to the 2950 and only shared access to vlan 1 on that trunk (since the 2950 is in the most basic configuration and does not know about the new voice vlan).
On the 2950, I added the following configuration for the trunk:
interface FastEthernet0/24
description Trunk to 3750
switchport trunk allowed vlan 1
switchport mode trunk
On the 3750, here are the trunk port and eigrp configs:
interface FastEthernet0/48
description Trunk to 2950
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1
switchport mode trunk
router eigrp 200
no auto-summary
no eigrp log-neighbor-changes
network 10.1.1.0
network 10.1.100.0
When I added the switch to the network, I was able to access the 10.1.10 data network to the new switch, however, the EIGRP routes were not showing up in the 3750, and the new voice vlan could not be accessed from anywhere else on the network.
I have a feeling it may be the configuration of the trunk between the 3750 and the 2950.
Any advice or recommendations are appreciated.
Thank you friends.
