Hello braintrust. This is a pretty cool one here.
I have been tasked by a Customer to test Dual Core switch Failover for some Web servers for a Data Center. These Web SErvers use an bonding driver which effectively lets you have two NIC cards that someone with the driver host a VIP.
I have had to create a Test Environment of sorts; they have a QA environment where there are some 3750 switches. These switches do have some VLAN's on them.
Do create a test scenario to test HSRP failover, what I did was turn on VTP between switches, then created a VLAN 4. On each of the switches that will receive a connection from the server (effectively call them switch 1 and switch 2), I have created an interface in VLAN 4. SW.1 has an IP of 192.168.4.1; the SW.2 has an IP of 192.168.4.2, then I have standby commands for HSRP using "standby ip 192.168.4.3".
My question is this: Should I have a preempt statement on each VLAN 4 interface on each switch, or does it only go on the primary sw vlan???
thx...
