Hsrp Network Diagram With 3 Switch

Hsrp vlan support was added in cisco ios release 11 1 for ieee 802 10 secure data exchange sde and in cisco ios release 11 3 for cisco inter switch link isl.

Hsrp network diagram with 3 switch. 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. Priority this range is from 1 to 255 where 1 denotes the lowest priority and 255 denotes the highest priority. 3 optionally you can also enable preemption on the router using below command. On the diagram it s from pc vlan 2 to pc net.

R1 will be active for network one while r2 will be active for network two. By configuring multiple hsrp groups on a single interface hsrp load balancing can be achieved. Ethernet several ethernet lance and quicc controllers in low end products can only have a single unicast mac address in their address filter. Create a test vlan for hsrp and isolated vlan to switch with hsrp routers.

Cable between 2950 and switcha is disconnected cable between 2950 and switchb is disconnected. Break fec ports into single connected ports. We ping from a pc in vlan2 to a pc on internet. The standby priority standby preempt and standby track interface configuration commands are all used to set characteristics for finding active and standby routers and behavior regarding.

A good example is the above network diagram. 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. The use of hsrp in the network still exist but less prevalent nowadays.

For our example let s add pc2 to the lab setup. Disconnect all redundant ports. Reduce hsrp group members to only two members. If you stack the core distro together then you can do away with hsrp.

We ve tested the following case of cable failure. Core distro switches are 3560. Here attached the diagram of our lab hsrp lab jpg the config on routers and switches conf hsrp txt. Disconnect connected switches in the network until the problems cease.

The default priority value is 100. Prune trunk ports such that only necessary vlans propagate across those ports. When you run the hot standby router protocol hsrp between two routers connected via a lan switch you may observe instability in hsrp. The router in the hsrp group with the highest priority value becomes the active router.

For explanation sake we will call hsrp group 1 network one and hsrp group 2 network two. An hsrp address 10 10 10 3 will be also configured on both routers. 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.
