Cisco 3750 communication to a remote device on a separate vlan
Posted on 2011-03-04
I have a cisco 3750 stack (3 switches - 2 gigabit and one fast ethernet), configured for 3 VLANS and eigrp.
At the other end I have a cisco IE3000 switch. The 3750 is connected to the ie3000 via gigabit ports configured as trunk ports.
Here is the config on the 3750 stack for the VLAn's and eigrp:
ip address 10.100.20.4 255.255.255.0
standby 1 ip 10.100.20.2
standby 1 preempt
ip address 10.100.2.4 255.255.255.0
standby 100 ip 10.100.2.2
standby 100 preempt
ip address 10.100.24.4 255.255.255.0
standby 103 ip 10.100.24.2
standby 103 preempt
router eigrp 100
ip route 0.0.0.0 0.0.0.0 10.100.2.253
I am connecting a computer using an IP address for VLAN100 on a 3750 fast ethernet port. I can't ping a device connected to the ie3000 switch. If I connect this PC locally on the ie3000 switch using a VLAN103 ip, I can ping the device.
Why can't a ping the remote device on VLan103?
