EIGRP issue using VRF on 3850

jmperlewitz

Level 1

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:

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.
