    Configuring VRRP Configuring VRRP This section describes how to configure HP 9300M routers to use Virtual Router Redundancy Protocol (VRRP), a standard protocol described in RFC 2338. Details for configuring VRRP with the CLI and the Web management interface are shown. For complete syntax information for CLI commands, see appendix B, "Command Line Interface Commands"...
  • Page 6: Virtual Router Id (Vrid)

    Configuring VRRP Figure 2 shows the same example network shown in Figure 1, but with a VRRP virtual router configured on Router1 and Router2. Figure 2 Router1 and Router2 are configured as a VRRP virtual router to provide redundant network access for Host1 The dashed box in Figure 2 represents a VRRP virtual router.
  • Page 7: Virtual Router Mac Address

    Configuring VRRP Virtual Router MAC Address Notice the MAC address associated with VRID1. The first five octets of the address are the standard MAC prefix for VRRP packets, as described in RFC 2338. The last octet is the VRID. THE VRID number becomes the final octet in the virtual MAC address associated with the virtual router.

    Track Ports and Track Priority The HP implementation of VRRP enhances the protocol by giving a VRRP router the capability to monitor the state of the interfaces on the other end of the route path through the router. For example, in Figure 2, interface e1/6 on Router1 owns the IP address to which Host1 directs route traffic on its default gateway.
  • Page 9: Suppression Of Rip Advertisements For Backed Up Interfaces

    HP’s implementation of VRRP supports authentication using simple clear text passwords. SRP does not support authentication. NOTE: If your HP routing switches already are using SRP and you do not need redundancy with devices that cannot use SRP, you do not need to reconfigure to use VRRP.
  • Page 10: Configuring Vrrp

    Configuring VRRP Configuring VRRP To configure a router for VRRP, do the following: Enable VRRP on the router. Indicate the authentication method used for the interface on which you are configuring the VRID (optional). VRRP uses the authentication method in use on the interface. Add a VRID to an interface.
  • Page 11: Configuring A Virtual Router

    Configuring VRRP USING THE WEB MANAGEMENT INTERFACE To enable VRRP on a router: Select the System link from the main menu to display the panel shown in “Configuring a Virtual Router” on page 11. Enable VRRP on the System configuration sheet. Select the Apply button to assign the changes.
  • Page 12 Configuring VRRP Configuring Router2 Using the CLI To configure Router2 in Figure 2 after enabling VRRP, enter the following commands: Router2(config)# inter e 1/5 Router2(config-if-1/5)# ip vrrp vrid 1 Router2(config-if-1/5-vrid-1)# backup priority 100 track-priority 19 Router2(config-if-1/5-vrid-1)# track-port ethernet 3/2 Router2(config-if-1/5-vrid-1)# ip-address 192.53.5.1 Router2(config-if-1/5-vrid-1)# activate The backup command specifies that this router is a VRRP Backup for virtual router VRID1.
  • Page 13 Configuring VRRP Enter the Hello interval or leave the field unchanged to use the default. The software fills in the default after you select Add. In this example, leave the field unchanged. Select the mode (Owner or Backup). Select Owner in this example. Select Enable to activate the VRRP entry after you select Add.
  • Page 14 Configuring VRRP Enter the Hello interval or leave the field as is to use the default. The software fills in the default after you select Add. In this example, leave the field unchanged. Select the mode (Owner or Backup). Select Backup in this example. Select Enable to activate the VRRP entry after you select Add.

    Authentication Type If the interfaces on which you configure the VRID use authentication, the VRRP packets on those interfaces also must use the same authentication. HP’s implementation of VRRP supports the following authentication types: • No authentication – The interfaces do not use authentication. This is the VRRP default.
  • Page 16 Configuring VRRP Router Type A VRRP router is either an owner or a Backup. By default, the owner becomes the Master following the negotiation. A Backup becomes the Master only if the Master becomes unavailable. NOTE: The IP address(es) you associate with the owner must be a real IP address (or addresses) on the interface on which you configure the VRID.
  • Page 17 Configuring VRRP Suppression of RIP Advertisements on Backup Routers for the Backup Up Interface Normally, a VRRP Backup router includes route information for the interface it is backing up in RIP advertisements. As a result, other routers receive multiple paths for the interface and might sometimes unsuccessfully use the path to the Backup rather than the path to the Master.
  • Page 18 Configuring VRRP Track Port You can configure the VRID on an interface to track another interface on the router. This is quite useful for tracking the state of the exit interface for the path for which the VRID is providing redundancy. See “Track Ports and Track Priority”...
  • Page 19: Displaying Vrrp Configuration Information And Statistics

    You can use the CLI or Web management interface to display configuration information and statistics for VRRP. Displaying Configuration Information To display VRRP configuration information for an HP routing switch, use one of the following methods. USING THE CLI To display VRRP configuration information for a router, enter the following command:...
  • Page 20 Configuring VRRP Figure 5 VRRP configuration information for owner NOTE: If the parameter is not defined or does not apply to this type of entry, the field is blank. For example, in Figure 5, the Backup Priority parameter does not apply to this entry because the entry is for an owner. Figure 6 VRRP configuration information for Backup Each display shows a separate set of information for each VRRP interface configured on the router.
  • Page 21: Displaying Vrrp Statistics

    Configuring VRRP Displaying VRRP Statistics Use the following methods to display VRRP statistics. NOTE: It is normal for the VRRP statistics to be zero. Zeros indicate that no errors have occurred and that the owner is still the Master. USING THE CLI To display VRRP statistics for a router, enter the following command: Router1(config)# show ip vrrp stat Here is an example of the information displayed by this command:...

    Select Clear from the System configuration sheet. Select VRRP. Select Apply. Quality of Service (QoS) Algorithms This section describes the Quality-of-Service (QoS) algorithms used by the HP 9300M routing switches. You can apply QoS priorities to the following: • Ports •...
  • Page 23: Qos Priorities

    Quality of Service (QoS) Algorithms QoS Priorities You can select one of the following priorities: • 0 or 1 – These priorities correspond to queue 0, the normal priority queue. • 2 or 3 – These priorities correspond to queue 1, a higher priority queue. •...
  • Page 24: Example Queue Cycle

    Quality of Service (QoS) Algorithms For the default weights, these calculations yield the following guaranteed minimum percentages: • p0 = 1.7% • p1 = 3.3% • p2 = 15% • p3 = 80% Example Queue Cycle You can compare the queue cycle to the operation of a gasoline pump with multiple dials. Some dials turn only once during a cycle and are triggered by the smaller dials, which turn multiple times during a cycle.
  • Page 25 Quality of Service (QoS) Algorithms Table 1:, “Queue time-line using default weights,” on page 25 shows the progress of packets through the queue at each stage in the rotation of the dials shown in Figure 9. Table 1: Queue time-line using default weights Queue 3 Queue 2 Queue 1...

  • Page 27 Quality of Service (QoS) Algorithms The weights of the lower queues determine how many times the next higher queue will chain to them before moving to an even lower queue. Because queue 2’s weight is 3, the algorithm chains from queue 3 to queue 2 three times before chaining farther down to queue 1.
