Routing between Switch and Server - EIGRP

[mahesh18]

                   Hi Everyone,

We have server directly connected to switch as access  port.

Server port config  on switch port

switchport access vlan 590
switchport mode access
spanning-tree portfast

Switch has SVI vlan 590 and it is up up.

Below is config of vlan 590

interface Vlan590

ip vrf forwarding XYZ

ip address 192.168.90.1 255.255.255.0

When i do sh ip route on switch with server ip it shows

sh ip route 192.168.90.110

Routing entry for 192.168.90.0/24

  Known via "eigrp 778", distance 170, metric 297245184, type external

  Redistributing via eigrp 778

  Last update from 172.20.100.110 on Vlan110, 7w0d ago

  Routing Descriptor Blocks:

  * 172.20.100.110, from 172.20.100.110, 7w0d ago, via Vlan110

      Route metric is 297245184, traffic share count is 1

      Total delay is 500030 microseconds, minimum bandwidth is 9 Kbit

      Reliability 255/255, minimum MTU 1476 bytes

      Loading 25/255, Hops 3

Here is shows Server is 3 Hops away need to  know how can i go further to trace the routing to each  HOP  between Switch and server.

thanks

Mahesh,

The route that you're showing is 192.168.90.110. I'm assuming that's the server? The question that I have is that the vlan590 belongs to a vrf, which if you were looking for the 192.168.90.x subnet, you would need to type "show ip route vrf XYZ 192.168.90.110". The 192.168.90.110 that you're seeing is possibly in the global routing table and not the routing table that you're wanting to see....

Hi John,

Thanks for reply back i did

sh ip route vrf XYZ 192.168.90.110
Routing entry for 192.168.90.0/24
  Known via "connected", distance 0, metric 0 (connected, via interface)
  Redistributing via eigrp 510
  Routing Descriptor Blocks:
  * directly connected, via Vlan590
      Route metric is 0, traffic share count is 1

So this shows that route belongs to vlan 590 right?

And this is directly connected to vlan 590 right ?

But one thing i need to tell you is that from that switch if we need to reach server subnet traffic goes via WAN  that is main office and comes back to switch then it goes to server.

So i was trying to trace the flow of traffic from switch to main office and back to switch

Need to know what is best way to do that?

Thanks

So i was try

Hi John,

Yes 192.168.90.110 is server IP.

Ah, I understand now (I think ). Have you tried traceroute? That's the easiest way. It will show you what routers the traffic is going through.

Hi John,

I did traceroute on switch here is info

  1  (172.20.100.110) 0 msec 0 msec 0 msec

  2 192.168.128.15 25 msec 17 msec 25 msec

  3  (172.16.250.20) 101 msec 58 msec 26 msec

after 3 hops it shows * * all the way.

172.20.100.110 is router connected to this switch.

That router has tunnel interface that has destination IP of  192.168.128.15 - This IP is at device in Main office.

172.16.250.20   is Cisco switch in main office

Seems that cisco device goes to fw thats why it does not go further.

thanks
