GLBP Configuration Sim
Tasks
Implement GLBP between DISTRO-SW1 and DISTRO-SW2 on VLAN 100 for hosts connected to ACCESS-SW1 to achieve these goals:
1. Configure group 1 using the virtual IP address of 192.168.1.254
2. Configure DISTRO-SW1 as the AVG using a priority value of 110
3. If DISTRO-SW1 suffers a failure and recovers, ensure that it automatically resumes the AVG role after waiting for a minimum of 15 seconds.
Topology
Solution
| You can practice this sim with our own online simulator or EVE-NG at: + GLBP Configuration online simulator + EVE-NG file (Note: Sometimes the VLAN information is missing when you import the EVE-NG lab so you may need to create the VLAN 100 again: Switch(config)#vlan 100 Switch(config-vlan)#exit //Must exit to apply the VLAN config) |
Note: The virtual IP address, priority, delay value … may be different so please check the question carefully.
DISTRO-SW1(config)#interface vlan 100
DISTRO-SW1(config-if)#glbp 1 ip 192.168.1.254
DISTRO-SW1(config-if)#glbp 1 priority 110
DISTRO-SW1(config-if)#glbp 1 preempt delay minimum 15 //Configures the router to preempt if it has a higher priority than the current active virtual forwarder after a delay of 15 seconds
DISTRO-SW2(config)#interface vlan 100
DISTRO-SW2(config-if)#glbp 1 ip 192.168.1.254
DISTRO-SW2(config-if)#glbp 1 preempt
Don’t forget to save the configs
