Best Practice regarding routing traffic to HSRP router ?

Hi,

​

First sorry for my english AND i'm far from a pro in networking this is mostly educational purpose so sorry if i say something stupid ... trying to improve myself :)

​

I got a question about the "best way" to forward traffic to 2 physical router configured as HSRP.

​

Here is a graph :

and here is more info :

​

Endpoint's GW are on SW03

SW03 got multiple VLAN configured with each their own subnet + SVI

Endpoint are on multiple VLAN

​

As far as i know about HSRP (and believe me that's few, i discovered it yesterday ...) it NEED to have a "leg" in each subnet.

it mean there is a need for 3 IP (2 physical + 1 virtual) in each VLAN for it to work.

​

my question/problem is :

in this case, the LAN rooting is done by SW03 is there a possiblity to make a roote from SW03 to VRRP WITHOUT the need to assign 3 IP in each subnet AND configure all ip/vlan/subnet on the router(s) ?

And obviously keeping the high availability of HSRP.

​

well, writing this post i realised that there is still a need to 2 connections from SW03 (2 physical router) hence the "graph" is false so now i'm thinking this post is useless xD

​

regardless here is the rought idea i HAD before while i was writing this post :

SW03 :

int gig1/0/24

int gig1/0/24 no switchmode

int gig1/0/24 ip address 192.168.100.2

ip route 0.0.0.0 0.0.0.0 192.168.100.1

​

Router(s)

int G0.0 ip address 192.168.100.1

ip route 0.0.0.0 0.0.0.0 192.168.100.2

​

If anyone can confirm there is no other way that 3 Ip/vlan to maintain HSRP thay would still be a mini win ;)

if there is another way ... i'd be glad to hear it ! :)

​

thanks in advance
