Cisco 3550's, will this work?
Hi,
I have two CISCO 3550-24-SMI Layer 3 switches and I'm trying to create a Fault Tolerant / Load Balanced setup for a network with two VLANS. When both switches are in operation I want them to load balance, but if a switch fails then I need fault tolerence.
The switches are set to be Primary and Standby and have a GigaStack Link between them. They have two VLANS defined, VLAN1 (192.168.100.*) is used to connect 3 Servers (all of which have dual NICS set to Fault Tolerence with Load Balancing), VLAN2 (192.168.200.*) provides a redundant uplink (2 Cat5 cables, one from each 3550 into a 2900 Switch) to an existing network with other clients that connect through to VLAN1 for server resources.
VLAN1 has a virtual IP of 192.168.100.1 with 3550-A being 192.168.100.2 and 3550-B being 192.168.100.3. VLAN2 has a virtual IP of 192.168.200.1 with 3550-A being 192.168.200.2 and 3550-B being 192.168.200.3. Routing between the VLANS is working fine.
I have a diagram:
I have a couple of questions, which are:
1) Are there going to be any problems with the way the 2900 is connected to the 3550's.
2) Does anybody have any config tips or know of any resources on the web that discuss setting up 3550's this way.
Thank you in advance for any help.
