R0106-HP MSR Router Series High Availability Configuration Guide(V7)

Configuration procedure

1. Configure the IP address of each interface as shown in Figure 21. (Details not shown.)

2. Configure an NQA operation on Router A:

# Create an NQA operation with the administrator name admin and the operation tag test.

<RouterA> system-view

[RouterA] nqa entry admin test

# Configure the operation type as ICMP echo.

[RouterA-nqa-admin-test] type icmp-echo

# Configure the destination address as 10.1.2.2.

[RouterA-nqa-admin-test-icmp-echo] destination ip 10.1.2.2

# Configure the ICMP echo operation to repeat at an interval of 100 milliseconds.

[RouterA-nqa-admin-test-icmp-echo] frequency 100

# Create reaction entry 1, specifying that five consecutive probe failures trigger the Track module.

[RouterA-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail

threshold-type consecutive 5 action-type trigger-only

[RouterA-nqa-admin-test-icmp-echo] quit

# Start the NQA operation.

[RouterA] nqa schedule admin test start-time now lifetime forever

3. On Router A, configure track entry 1, and associate it with reaction entry 1 of the NQA operation.

[RouterA] track 1 nqa entry admin test reaction 1

4. Configure VRRP on Router A:

# Specify VRRPv2 to run on the interface GigabitEthernet 2/0/1.

[RouterA] interface gigabitethernet 2/0/1

[RouterA-GigabitEthernet2/0/1] vrrp version 2

# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 virtual-ip 10.1.1.10

# Set the priority of Router A in VRRP group 1 to 110.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 priority 110

# Set the authentication mode of VRRP group 1 to simple, and the authentication key to hello.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 authentication-mode simple plain hello

# Configure the master to send VRRP packets at an interval of 500 centiseconds.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 timer advertise 500

# Configure Router A to operate in preemptive mode, and set the preemption delay to 5 seconds.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 preempt-mode delay 5

# Associate VRRP group 1 with track entry 1 and decrease the router priority by 30 when the state

of track entry 1 changes to negative.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 track 1 reduced 30

5. Configure VRRP on Router B:

# Specify VRRPv2 to run on the interface GigabitEthernet 2/0/1.

<RouterB> system-view

[RouterB] interface gigabitethernet 2/0/1

[RouterB-GigabitEthernet2/0/1] vrrp version 2

# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.

[RouterB-GigabitEthernet2/0/1] vrrp vrid 1 virtual-ip 10.1.1.10
