VRID VRRP group number.
reset vrrp ipv6 statistics Use reset vrrp ipv6 statistics to clear statistics for IPv6 VRRP groups. Syntax reset vrrp ipv6 statistics [ interface interface-type interface-number [ vrid virtual-router-id ] ] Views User view Predefined user roles network-admin Parameters interface interface-type interface-number: Specifies an interface by its type and number. vrid virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
Parameters virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255. delay delay-value: Specifies a preemption delay time in the range of 0 to 255, in seconds. The default setting is 0 seconds. Usage guidelines In non-preemptive mode, when a router in the IPv6 VRRP group becomes the master, it acts as the master as long as it operates correctly, even if a backup is assigned a higher priority later.
Usage guidelines VRRP determines the role (master or backup) of each router in a VRRP group by priority. A router with a higher priority is more likely to become the master. The VRRP priority is in the range of 0 to 255. A greater number represents a higher priority. Priorities 1 to 254 are configurable. Priority 0 is reserved for special uses, and priority 255 is for the IP address owner.
vrrp ipv6 vrid timer advertise Use vrrp ipv6 vrid timer advertise to configure the interval at which the master in an IPv6 VRRP group sends VRRP advertisements. Use undo vrrp ipv6 vrid timer advertise to restore the default. Syntax vrrp ipv6 vrid virtual-router-id timer advertise adver-interval undo vrrp ipv6 vrid virtual-router-id timer advertise Default The master in an IPv6 VRRP group sends VRRP advertisements at an interval of 100 centiseconds.
vrrp ipv6 vrid track Use vrrp ipv6 vrid track to associate an IPv6 VRRP group with a track entry and control master switchover in the VRRP group in response to changes (such as uplink state changes) detected by the track entry. Use undo vrrp ipv6 vrid track to remove the association between an IPv6 VRRP group and a track entry. If no track entry is specified, the association between the VRRP group and any track entry is removed.
Examples # Associate IPv6 VRRP group 1 on VLAN-interface 2 with track entry 1 and decrease the priority of the router in the VRRP group by 50 when the state of track entry 1 changes to negative.
Examples # Create IPv6 VRRP group 1 and assign virtual IPv6 address fe80::10 to the VRRP group. Then assign virtual IPv6 address 1::10 to the VRRP group.
BFD commands The term interface in the BFD feature refers to Layer 3 interfaces, including VLAN interfaces and Layer 3 Ethernet interfaces. You can set an Ethernet port as a Layer 3 interface by using the port link-mode route command (see Layer 2—LAN Switching Configuration Guide). bfd authentication-mode Use bfd authentication-mode to configure the BFD authentication mode for single-hop BFD control packets. Use undo bfd authentication-mode to restore the default.
bfd demand enable Use bfd demand enable to enable the Demand BFD session mode. Use undo bfd demand enable to restore the default. Syntax bfd demand enable undo bfd demand enable Default The BFD session is in Asynchronous mode. Views Interface view Predefined user roles network-admin Usage guidelines In demand mode, no BFD control packets are exchanged after the session is established.
Parameters value: Specifies a single-hop detection time multiplier in the range of 3 to 50. Usage guidelines The detection time multiplier determines the maximum number of concurrent BFD packets (including control packets and echo packets) that can be discarded. Table 24 shows the detection interval calculation methods.
[Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] bfd echo enable bfd echo-source-ip Use bfd echo-source-ip to configure the source IP address of BFD echo packets. Use undo bfd echo-source-ip to remove the configured source IP address of BFD echo packets. Syntax bfd echo-source-ip ip-address undo bfd echo-source-ip Default No source IP address is configured for BFD echo packets.
Parameters ipv6-address: Specifies the source IPv6 address for BFD echo packets. Usage guidelines The source IPv6 address of echo packets can only be a global unicast address. The source IPv6 address cannot be on the same network segment as any local interface's IP address. Otherwise, a large number of ICMP redirect packets may be sent from the peer, resulting in link congestion. Examples # Configure the source IPv6 address of BFD echo packets as 80::2.
Use undo bfd min-receive-interval to restore the default. Syntax bfd min-receive-interval value undo bfd min-receive-interval Default The minimum interval for receiving single-hop BFD control packets is 1000 milliseconds. Views Interface view Predefined user roles network-admin Parameters value: Specifies the minimum interval for receiving single-hop BFD control packets, in milliseconds. The value range for this argument is 100 to 1000.
Parameters value: Specifies the minimum interval for transmitting single-hop BFD control packets, in milliseconds. The value range for this argument is 100 to 1000. Usage guidelines Use this command to make sure that the BFD packet sending rate does not exceed the device capability.
Examples # Configure the simple authentication mode for multi-hop BFD control packets, setting the authentication key ID to 1 and password to 123456. system-view [Sysname] bfd multi-hop authentication-mode simple 1 plain 123456 bfd multi-hop destination-port Use bfd multi-hop destination-port to configure the destination port number for multi-hop BFD control packets. Use undo bfd multi-hop destination-port to restore the default.
Parameters value: Specifies the multi-hop detection time multiplier in the range of 3 to 50. Usage guidelines The detection time multiplier determines the maximum number of concurrent BFD control packets that can be discarded. Table 25 shows the detection interval calculation methods.
Examples # Configure the minimum interval for receiving multi-hop BFD control packets as 500 milliseconds. system-view [Sysname] bfd multi-hop min-receive-interval 500 bfd multi-hop min-transmit-interval Use bfd multi-hop min-transmit-interval to configure the minimum interval for transmitting multi-hop BFD control packets. Use undo bfd multi-hop min-transmit-interval to restore the default.
Views System view Predefined user roles network-admin Parameters active: Uses the active mode. In active mode, BFD actively transmits BFD control packets to the remote device, regardless of whether it receives a BFD control packet from the remote device. passive: Uses the passive mode. In passive mode, BFD does not actively transmit a BFD control packet to the remote end; it transmits a BFD control packet only after receiving a BFD control packet from the remote end.
