Hi expert,
This might be a stupid question.
See below scenario:
Let say i have two access switches connected on 1 router with one vlan, and i want to run some sort of redundancy protocol such as HSRP on the router for that vlan using some sort of vrf configuration. Is that possible?
I know i can install a second router and configure HSRP between the two devices but we are a bit tight on budget, and will take a while to acquire a second device.
So is it possible to run HSRP for one vlan on a single device?
It doesn't have to be vrf, it can be anything. I was just thinking of vrf because it was the only thing that came to mind :)
Thanks in advance,
Regards,
Steve

Hello Mate !
Not a usual scenario for hsrp, since we usually have two routers providing real redundancy for the scenario
Your scenario is something like this(correct me if i am wrong):
<ROUTER>
/ \
/ \
<SW1> ---------- <SW2>
Your L3 device is the router, probably a VLAN interface, correct ? Configuring a hsrp in this unique vlan wont help, unfortunately !
I am afraid your only redundancy in this case will be the inter switch link, in case the uplink betwen one of the switches and the router goes down.
i hope this helps
cheers

Hi
I haven't done this myself, but I think it can be done with the use of IRB.
Configure an interface bvi1( ip address ), and on the physical interfaces configure bridge-group1
