How many groups can be created in HSRP?
Hot Standby Router Protocol (HSRP) has 2-versions : This version allows group number range from 0 to 255.
What is Cisco HSRP configuration?
Hot Standby Router Protocol (HSRP) provides redundancy for IP networks, ensuring that user traffic immediately and transparently recovers from first hop router failures. HSRP allows multiple routers on a single LAN to share a virtual IP and MAC address which is configured as the default gateway on the hosts.
Can Layer 3 switch use HSRP?
Hot Standby Router Protocol (HSRP) is a Cisco proprietary protocol that allows several routers or multilayer switches to appear as a single gateway IP address. It provides redundancy for the layer 3 functions in our networks.
How do you do load balancing in HSRP?
To achieve load balancing with this HSRP setup, half of the hosts in VLAN 100 must point to the first virtual address as their gateway – 10.1. 1.1. The other half must use the other virtual address as their gateway – 10.1. 1.254.
What is the default priority value in HSRP?
Router with the the highest priority become the Active Router immediately. Priority is determined first by the value that is configured at the interface, and then by highest interface IP address. Default priority is set to 100.
What is HSRP and how do I use it?
HSRP is used within a group of routers in order to select an active router and a standby router. In a group of router interfaces, the active router is the router of choice for routing packets; the standby router is the router that takes over when the active router fails or when preset conditions are met.
How will HSRP be configured between interfaces fe0/1 and RTR-a/B?
From the diagram above, HSRP will be running between interfaces FE0/1 on the two LAN routers. Interface FE0/1 on RTR-A will have a physical IP address 10.10.10.1 and interface FE0/1 on RTR-B will have a physical IP address 10.10.10.2. An HSRP address 10.10.10.3 will be also configured on both routers.
How many gateway routers can we have with HSRP?
With HSRP we can have two gateway routers, one active and one standby, which will provide resiliency regarding the default gateway address.
Does HSRP require L2 connectivity?
Remember that for HSRP to work, we need to provide Layer2 connectivity between the routers. The two switches on the LAN side and the two switches on the WAN side will provide the required L2 connectivity for HSRP to run on both the LAN and WAN connections.
