Question about HSRP configuration.

[jared1995]

For an HSRP configuration at the distribution level, in terms of speed which is a better configuration?

a) Routing an additional IP address block to the standby IP address, or

b) Adding the additional IP address block as a secondary IP address in the Vlan interface.

Thank you for your input.

Hi,

I would suggest configure a seperate vlan for HSRP. I have configured vlan-1 and use this for HSRP like below..

ACTIVE:

interface Vlan1
ip address 10.10.1.2 255.255.0.0
standby 0 ip 10.10.1.1
standby 0 priority 105
standby 0 preempt

STANDBY:

interface Vlan1
ip address 10.10.1.3 255.255.0.0
standby 0 ip 10.10.1.1
standby 0 preempt

Hope the above clear and understood.

Latchum,

Thank you for your input.

My setup is already HSRP and we adding a new IP block to the same network (and probably more IP blocks in the future)

My question is, in terms of speed which configuration would work better?

adding the ip block as secondary to the vlan interface.

ip address 10.10.49.128 255.255.255.248 secondary

Or, routing this block to the standby IP address on both distro routers.

ip route 10.10.49.128 255.255.255.248 10.10.49.29

(where 10.10.49.29 is the standby IP of HSRP)

Once again thank you.

Hi,

OK...I would prefer adding new subnet as secondary to the vlan.

VLAN 43
ip address 10.10.1.1
ip address 10.10.2.1 secondary

Like above You can have many secondary IP addresses. I have never heard of a limit.
