STP and HSRP Configuration

A. STP(Spanning Tree Protocol)

command: spanning-tree VLAN 1 root primary ( Vlan1 Root bridge)

spanning-tree VLAN 2 root secondary ( vlan2 backup bridge)

two. Hot Backup Route selection protocol (HSRP)

Cisco the private protocol.

Lab Environment:

Configuration HSRP two three-layer switches, the VLAN IP The address cannot be the same, but the virtual IP must be the same, the same VLAN , HSRP The group must be the same.

Network planning:

1. 1. in the SW1 of the Switch VLAN physical of virtual interfaces IP Address:

Vlan 2:192.168.2.1/24

Vlan 3:192.168.3.1/24

1. 2. in the SW2 of the Switch VLAN physical of virtual interfaces IP Address:

Vlan 2:192.168.2.2/24

Vlan 3:192.168.3.2/24

1. 3. PC1of theIPaddress is192.168.2.10/24, the gateway is192.168.2.254/24;PC2of theIPaddress is192.168.3.10/24, the gateway is192.168.3.254/24.

3. 4.      SW1 and 192.168.0.0/30 sw2 r2 192.168.1.0/30

5. 5.      Configure r1 loopback ip 192.168.100.1/24

7. 6. links between switches for the relay link ( Trunk ), and use static routing for Network interoperability.

Experimental steps:

2. 1.      Configure basic information for devices (interfaces Span style= "FONT-SIZE:16PX;" >ip address, vlan trunk , routing, etc configuration)

4. 2. Configuration HSRP :

SW1 Configuration:

int VLAN 2 (and configure IP address)

Standby 2 IP 192.168.2.254 Configure virtual IP Address

Standby 2 Priority Configuration Priority

Standby 2 preempt Configure preemptive rights

stanyby 2 track F0/1 Configure Port tracking

stanyby 2 track F0/14 Configure Port tracking

Int VLAN 3 (and configure IP address, priority default - , no port tracking required)

Standby 3 IP 192.168.3.254

Standby 3 Preempt

Sw2 Configuration:

int VLAN 2 (and configure IP address)

Standby 2 IP 192.168.2.254

Standby 2 preempt

int VLAN 3 (and configure IP address)

Standby 3 IP 192.168.3.254

Standby 3 Priority 150

Standby 3 preempt

Standby 3 track F0/1 100

Standby 3 track F0/14 100

1. 3. Configuration STP Implement VLAN load Balancing.

SW1 Configuration:

Spanning-tree VLAN 2 Root Primary

Spanning-tree VLAN 3 Root Secondary

Sw2 Configuration:

Spanning-tree Valn 2 Root Secondary

Spanning-tree VLAN 3 Root Primary

1. 4. Validation HSRP
