Gateway redundancy Load Balancing

HSRPcisco and VRRP are the most common gateway redundancy technologies. Similar to VRRP, HSRP is composed of multiple routers.

A vro is a virtual gateway, and a vro is active.

It is replaced by a device to implement transparent switching to users. However, we hope to achieve redundancy at the same time.

Load Balancing to make full use of the capabilities of the device, GLBP (cisco) provides both redundancy and load balancing capabilities.

The configuration steps are as follows:

Configure relevant ports, configure tracking, set gateway groups, set gateways based on different traffic, and set different priorities for mutual traffic distribution and replacement.

Hsrp

Router:

Interface f0/0

No shut

Ip add 192.168.0.1 255.255.255.0

Standby 1 ip 192.168.0.254

Standby 1 preempt

Standby 1 priority 120

Standby 1 track f0/1 30

Standby 1 authentication md5 key-string cisco

Standby 2 ip 192.168.0.253

Standby 2 preempt

Standby 2 authentication md5 key-string cisco

Router B:

Interface f0/0

No shut

Ip address 192.168.0.2 255.255.255.0

Standby 1 ip 192.168.0.254

Standby 1 preempt

Standby 1 authentication md5 key-string cisco

Standby 2 ip 192.168.0.253

Standby 2 authentication md5 key-string cisco

Standby 2 priotiry 120

Standby 2 track f0/1 30

Vrrp

Router:

Track 100 interface f0/1 line-protocol

Interface f0/0

Vrrp 1 ip address 192.168.0.254

Vrrp 1 priority 120

Vrrp 1 preempt

Vrrp 1 authentication md5 key-string cisco

Vrrp 1 track 100 decrement 30

Vrrp 2 ip address 192.168.0.253

Vrrp 2 preempt

Vrrp 2 authentication md5 key-string cisco

Router B:

Track 100 interface f0/0 line-protocol

Interface f0/0

Vrrp 1 ip address 192.168.0.254

Vrrp 1 preempt

Vrrp 1 authentication key-string cisco

Vrrp 2 ip address 192.168.0.253

Vrrp 2 preempt

Vrrp 2 priority 120

Vrrp 2 track 100 decrement 30

Vrrp 2 authentication md5 key-string cisco

Router:

Int f0/0

Glbp 1 ip address 192.168.1.254

Glbp 1 priority 200

Glbp 1 preempt

Glbp 1 authentication md5 key-string cisco

Router B:

Int f0/0

Glbp 1 ip address 192.168.1.254

Glbp 1 priority 180

Glbp 1 preempt

Glbp 1 authentication md5 key-string cisco

In this way, Gateway redundancy and load balancing can be achieved.
