Hello all,
We have a 4451 router which runs an integrated zone-based firewall. We connect 2 physical interfaces via Port-channel to our core switch (3850). We run a separate VRF for each zone on the switch so that is has it's own routing table. We currently are using OSPF for our IGP with success.
However, I would like to setup EIGRP routing as well but I am having difficulty getting the VRF vlans to establish a neighbor relationship. I can get the vlan that is not associated with any VRF to establish a neighbor relationship fine. See my relevant info below:
4440:
Port-channel2 unassigned Port-channel2.101 10.10.101.1 Port-channel2.103 10.10.103.1 Port-channel2.105 10.10.105.1 Port-channel2.107 10.10.107.1 Port-channel2.109 10.10.109.1 Port-channel2.111 10.10.111.1
3850:
Vlan101 10.10.101.2 Vlan103 10.10.103.2 Vlan105 10.10.105.2 Vlan107 10.10.107.2 Vlan109 10.10.109.2 Vlan111 10.10.111.2
VRFs:

Vlan interfaces:
interface Vlan101 description Internal_Infra ! interface Vlan103 description xxx_Infra vrf forwarding 103 ! interface Vlan105 description xxx_Infra vrf forwarding 105 ! interface Vlan107 description xxx_Infra vrf forwarding 107 ! interface Vlan109 description xxx_Infra vrf forwarding 109 ! interface Vlan111 description xxx_Infra vrf forwarding 111
OSPF reference:
We create separate OSPF processes for each vrf and it works fine

Any suggestions?

Hi,
Can you check VRF Name assigned in the switch is correct?
router eigrp 104 ! address-family ipv4 vrf POS autonomous-system 104 network 10.10.103.0 0.0.0.3 passive-interface default no passive-interface Vlan103 exit-address-family
But your VRF configuration is showing some other name:
Name Default RD Protocols Interfaces 109 <not set> ipv4,ipv6 Vl109 105 <not set> ipv4,ipv6 Vl105 Mgmt-vrf <not set> ipv4,ipv6 Gi0/0 111 <not set> ipv4,ipv6 Vl111 103 <not set> ipv4,ipv6 Vl103 107 <not set> ipv4,ipv6 Vl107
and Share the Switch configuration and check that zone-based firewall is not blocking eigrp.
