I have successfully set up Intervalna routing in a test environment between three test VLAN's. I have a 3750G 13 port switch acting as a distribution switch and have three other 3750's in a stack hanging off of it. I have enabled eigrp on the 12 port distibution switch and have announced the networks that are available. I also configured the switch to notice and route between three vlans. vlan 1: 172.16.225.4 255.255.0.0(native vlan) vlan 25: 10.10.10.1 255.255.255.0 vlan 20: 10.10.9.1 255.255.255.0 VTP domain is setup properly and trunking is configured as well. On the stack switch all ports except three are assigned to vlan 25. I used the command switcport mode access then followed it up by switchport access vlan
- The other port is assigned to vlan 20 using the previous commands and substituting 25 for 20. The last two are in a etherchannel trunking back to the distributuin switch carrying vlan 25, 20 and 1. Now I can ping every address available from the switches. Form any PC I can ping for a little while, then it stops. I have to reboot the distribution switch in order to get things working again, then it will eventually stop too.
Has anyone experienced anything similiar with these 3750 switches? I am about to try another switch in its place.
