HSRP

Function: run between multiple gateways on the same network segment, and the protocol can form a virtual gateway

At the same time, the load balance of data can be realized.

Master device: active backup device: standby

1. Devices participating in gateway virtualization are given priority first. The bigger the better. The default is 100.

2. If the priority is the same, compare the IP address. The larger the better.

3Perfect HSRP is a proprietary protocol of Cisco, which is not supported by other manufacturers' devices.

4Perfect HSRP does not enable preemption by default. For main devices, it must be enabled.

5For HSRP supports multiple link tracking technology

How to configure HSRP:

Enable HSRP on the gateway port and configure virtual gateway technology

Interface g0/0

Standby 10 ip 192.168.10 . two hundred and fifty

2. On the main gateway port, adjust the priority of HSRP as large as possible:

GW1 interface g0/0

Standby 10 priority 105

3. Enable the preemption feature of HSRP on the gateway port:

GW1 interface g0/0

Standby 10 preempt

4. Configure the gateway IP of the terminal device to be the IP address of the virtual gateway:

PC1 192.168.10.1 PC2 192.168.10.2

255.255.255.0 255.255.255.0

192.168.10.250 192.168.10.250

5, verification and testing

Debug ip icmp views message processing information of ICMP

In addition, HSRP external link tracking

When the external link of the gateway is disconnected, the HSRP will automatically lower the priority, and the reduction can be configured.

Interface g0/0

Standby 10 track interface g 0amp 1 [x]. Parameter x is available only in the real machine, indicating the manually specified amplitude.
