Loopbacks cant ping over trunk

nathan demers

DISCLAIMER**** (lol)OK so in our shop we dont do a lot of redesign so Im having a really hard time with this.  Its been a while.  Most of the changes we make are firewall changes and trunking.  Im having a huge brainfart on thsi.

To the point:  I am trying to ping across a trunk from one 3750 to another with loopbacks.    Where am I going wrong?

SW1

interface Vlan1983

ip address 192.168.83.1 255.255.255.240

interface Loopback1984

ip address 192.168.84.1 255.255.255.255

vlan 1983

name IT-OPS

router eigrp 1983

network 192.168.83.0 0.0.0.15

network 192.168.84.1 0.0.0.0

no auto-summary

interface FastEthernet1/0/13

switchport trunk encapsulation dot1q

switchport trunk native vlan 1983

switchport mode trunk

It is possible that there is more than one issue in this. But the first and most important issue that I see here is that there is not interface on switch 2 that would cause EIGRP to carry over the trunk.
