Hsrp Network Diagram With 3 Switches

By configuring multiple hsrp groups on a single interface hsrp load balancing can be achieved.

Hsrp network diagram with 3 switches. We ping from a pc in vlan2 to a pc on internet. Cable between 2950 and switcha is disconnected cable between 2950 and switchb is disconnected. On the diagram it s from pc vlan 2 to pc net. Break fec ports into single connected ports.

The 1 is the group number for hsrp. Now what happens if you have for example 3750 3650 3850 or 2960s x xr or a vss pair of 4500r e or 6500 6800 x chassis. This often happens during a network disruption or an active router transition such as an hsrp router with a higher priority and preempt configured being added to the lan. For our example let s add pc2 to the lab setup.

For explanation sake we will call hsrp group 1 network one and hsrp group 2 network two. Disconnect connected switches in the network until the problems cease. We will do this on the vlan 1 interfaces of sw1 and sw2. I was thinking about setting up hsrp on one interface of both switches but i imagine an ip route to the virtual ip address won t work because it is on the same switch.

This document explains why this instability occurs and how you can avoid it. When you run the hot standby router protocol hsrp between two routers connected via a lan switch you may observe instability in hsrp. Prune trunk ports such that only necessary vlans propagate across those ports. A good example is the above network diagram.

An hsrp address 10 10 10 3 will be also configured on both routers. The first thing we ll do is enable hsrp. Reduce hsrp group members to only two members. Ok in this video want to show all of you know how to design diagram and configure hsrp vlan vtp stp routing protocol.

We ve tested the following case of cable failure. R1 will be active for network one while r2 will be active for network two. We can see that coresw2 6509 has been selected as the active core switch local state is active the virtual core switch s ip is 156 50 196 1 and coresw1 6509 is the standby core switch. From the diagram above hsrp will be running between interfaces fe0 1 on the two lan routers.

Sw1 sw2 config interface vlan 1 config if standby 1 ip 192 168 1 254 use the standby command to configure hsrp. Each layer 3 cisco 3560 x is connected to an hp router that is managed by our isp. Create a test vlan for hsrp and isolated vlan to switch with hsrp routers. Controlling the active hsrp router there are more hsrp values that you ll need to change from time to time to ensure complete control over your network.

192 168 1 254 will be the virtual gateway ip address. Disconnect all redundant ports. 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. The use of hsrp in the network still exist but less prevalent nowadays.
