Hi,
I'm looking into changing the way we use HSRP in our network,
My Gold
I want to use standby 2 for all CUST1's SVI interfaces, and Standby 3 for all CUST2's SVI interfaces, and so on ...
Any recommendations ?? .. Is that the right way or ??
Snip of config.
interface vlan2
ip address 10.1.1.2 255.255.255.0
ip vrf forwarding CUST1
standby 2 preempt
standby 2 ip 10.1.1.1
!
interface vlan3
ip address 10.1.2.2 255.255.255.0
ip vrf forwarding CUST1
standby 2 preempt
standby 2 ip 10.1.2.1
interface vlan12
ip address 10.1.1.2 255.255.255.0
ip vrf forwarding CUST2
standby 3 preempt
standby 3 ip 10.1.1.1
!
interface vlan13
ip address 10.1.2.2 255.255.255.0
ip vrf forwarding CUST2
standby 3 preempt
standby 3 ip 10.1.2.1
Thanks in advance.

Hi Peter,
configuration looks absolutely fine, you should can also standby 2 times 5 15,standby 2 priority & standby 3 times 5 15,standby 3 priority, , so that your routers understands 1 as the ACTIVE router & the other as STANDBY.
hope this helps,

Hi Peter,
You can also think of having Customer 1 active on one L3 switch and Customer 2 active on second L3 switch by playing around with priority.
In this way all your customer 2 traffic will route through first router and all your customer 3 traffic will route through second router which will give you load balancing also and once any router goes down all traffic of both the cutsomer will start getting routed from available router.
You can have one router with high priority for vlan 2 and 3 on one router and on second router configure "standby priority

Hi
I think the original post was to confirm whether the same group number can be used for multiple HSRP interfaces.
The answer is yes. You can group 16 interfaces with a single HSRP group number.
The switch supports HSRP MAC addresses for up to 16 unique HSRP groups. Because each group address can be used on up to 16 Layer 3 interfaces, the maximum number of HSRP interfaces is 256
Each of the 16 HSRP MAC addresses can be used by 16 consecutive Layer 3 interfaces because each address is associated with a group of VLANs by using a 4-bit mask
For example, HSRP Group 1 might be assigned to interface VLANs 16 to 31, which equals the group maximum of 16 VLANs
See the link for more information
HTH, rate if it does
