Sync configuration HSRP

[hassamri]

Hello,

I have HSRP between 2 routers cisco and i would like to add a link of sync in order the configuration will be synchronise the moment we are doing a modifications on active router.

Someone can help me ?

Regards,

Tricky, since you cannot simply copy the entire configuration to the other device, you would need to exclude at the very least the interface IP addresses.

Have a llok at the thread below:

I know there are some commercial tools out there such as KIWI Cattools...

Are you referring to the ISR 4000's and their syncing capability?

Hi

Please correct me if I understanding wrong the question, but basically the link (point to point) can be used with a /30 to interconnect 2 routers and it will keep sync the HSRP, for example:

In this case OSPF will be used to interconnect both routers and to sync the HSRP process.  

ROUTER 1

interface g0/0

description TO-ROUTER2
ip address 10.0.0.1 255.255.255.252

interface g0/1

description LAN

ip address 192.168.12.2 255.255.255.0

standby 12 ip 192.168.12.1

standby 12 priority 105

router ospf 100

net 192.168.12.0 0.0.0.255 area 0

ROUTER 2

interface g0/0

You can modify this configuration to be adjusted to your network. 

Hope it is useful

I would like to know just the configuration that i will need in order to automate the synchro of configuration betweek the Active/Standby cisco router

Example of firewall (Palo Alto, Checkpoint, Pfsense) : in the cluster you have absolutly the link of synchro that permit to synchronise configuration when someone make a modification on active firewall.

like that i wabt to do but and i'm blocked.

Hi

The heartbeat Link usually are seen on firewalls or some devices supporting multichassis for replication so the standby will create a mirror of the active device. What you like to approach?
