Hello, I have a WS-C3750G-24T-S layer 3 switch and I need to configure independent routes for a specific network, I'm trying to use VRF but it is not working for me. I tried using route-map but it seems the switch doesn't support that, so I'm stuck with VRF, but I think I'm not doing it right. The topology is as follows:
I have a network directly connected to a vlan and I need to forward all the traffic I get on this VLAN using a tunnel to a router. I think the problem is that in order to use the tunnel I need to utilize another VLAN which isn't part of that VRF. I attach the configuration I'm using to better understand what I'm trying to do:
layer-3 switch:
ip vrf TEST
rd 1:1
interface Tunnel1
ip vrf forwarding TEST
ip address 172.17.0.1 255.255.255.252
tunnel source 10.245.0.9
tunnel destination 10.250.4.31
interface Vlan404
ip vrf select source
ip vrf receive TEST
ip address 10.250.4.1 255.255.255.0
ip ospf cost 32000
ip ospf hello-interval 2
ip ospf dead-interval 6
end
interface Vlan827
description access-patprimoquicentro
ip vrf forwarding TEST
ip address 10.245.0.9 255.255.255.248
ip route vrf TEST 0.0.0.0 0.0.0.0 Tunnel1
This is how my routing table looks for my VRF:
172.17.0.0/30 is subnetted, 1 subnets
C 172.17.0.0 is directly connected, Tunnel1
10.0.0.0/8 is variably subnetted, 3 subnets, 3 masks
S 10.250.4.31/32 [1/0] via 10.250.4.1
C 10.250.4.0/24 is directly connected, Vlan404
C 10.245.0.8/29 is directly connected, Vlan827
S* 0.0.0.0/0 [1/0] is directly connected, Tunnel1
this is my final end router:
interface Tunnel4
ip address 172.17.0.2 255.255.255.252
traffic-shape rate 512000 12800 12800 1000
tunnel source 10.250.4.31
tunnel destination 10.250.4.1
and this is how my routing table looks on this router:
172.17.0.0/30 is subnetted, 1 subnets
C 172.17.0.0 is directly connected, Tunnel4
C 10.250.4.0/24 is directly connected, Vlan404
S 10.245.0.8/29 [1/0] via 10.250.4.1
S* 0.0.0.0/0 [1/0] via 10.1.60.15
I hope you can help me out.
Thanks in advance
