#ASA ACTIVE STANDBY GNS3 CONFIGURATION MAC#

Actually, in most modern switches, it turns out that using the same standby number for multiple SVIs doesn’t affect the operation of HSRP at all.

I’ve never come across this, but it’s a very interesting thought experiment. Is this an accident waiting to happen ? What exactly could go wrong here if anything or is it ok to use the same hsrp standby number for each vlan SVI ? It seems to be working fine and have though about this and I assume as the traffic in the frame would be going to the correct location and then de-encapsulated to get the correct IP and then forward the traffic as normal then thats how this appears to be working fine or am I missing here ?

That obviously gives the same virtual mac address to every downstream device in each subnet - 01 So under every single SVI the standby group is “1”. Nothing strange there but what is strange is that the hsrp group numbers are configured with all the same number. I know the standby numbers dont need to match the vlans and I understand that the virtual mac will be with the xx being the group number in hex.īut I have recently came across a setup where there are a pair of switches running hrsp that have approx 10 vlans with SVI’s running hsrp as gateways for their downstream devices. If I have a pair of switches running hsrp and have 10 SVI’s running hsrp I assume best practice would be to create a unique hsrp group number for each SVI running hsrp. I understand the whole HSRP process and use it daily but I have recently came across an unusual setup.
