Topology:
In which OSPF is configured and every device can ping any other device now we have to configure High Availably protocol HSRP for that we will configure this on 192.168.10.5 router and 192.168.10.10 router.
High availability is a characteristic of a system, which aims to ensure operational performance, usually uptime, for a higher than normal period.
We will use HSRP (Hot Standby Routing Protocol) with the integration of IP SLA (Internet protocol service level agreement) for high availability.
What is IP SLA?
IP SLA (Internet protocol service level agreement) is a feature of the Cisco Internetwork Operating System (Cisco IOS) that allows an IT professional to collect information about network performance in real time.
What is HSRP?
In computer networking, the Hot Standby Router Protocol is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway.
Router 1:
Router 2:
Now if one side will down communication will automatically start from the other side.
HSRP is only for our side but what if the other side link down HSRP can’t tell you about that so we integrate HSRP with the IP SLA but we can’t Practice IP SLA in packet tracer.
