Configuring IPv6 OSPFv3 Interfaces in Gaia Clish

Important - In a ClusterClosed Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing., you must configure all the Cluster Members in the same way.

The configuration is applicable to OSPFv3 Multiple Instances (see Configuring IPv6 OSPFv3 Multiple Instances).

set ipv6 ospf3 [instance {<1-65535> | default}] interface <Name of Interface>

      area <OSPFv3 Area ID> {off | on}

      cost {<1-65535> | default}

      dead-interval {<1-65535> | default}

      hello-interval {<1-65535> | default}

      ip-reachability-detection {off | on}

      passive {off | on}

      priority {<0-255> | default}

      retransmit-interval {<1-65535> | default}

      security ipsec {off | spi <SPI>}

      virtual-address {off | on}

Parameter

Description

instance {<1-65535> | default}

Specifies the OSPFv3 instance.

interface <Name of Interface>

Specifies the name of the interface.

area <OSPFv3 Area ID> {off | on}

Disables (off) or enables (on) this OSPFv3 area on the interface.

cost {<1-65535> | default}

Configures the cost of using the given interface for a route.

The higher the cost, the less preferred the interface.

This is overridden by routing policy - Route Redistribution Rules and Route Maps.

Range: 1-65535, or default

Default: 1

dead-interval {<1-65535> | default}

Configures the time after receipt of the last Hello packet, at which a neighbor is declared dead.

Typically this is four times the Hello interval.

Important - For a given link, this value must be the same for all OSPFv3 routers.

Range: 1-65535 seconds, or default

Default: 40 seconds for broadcast networks, 120 seconds for point-to-point networks

hello-interval {<1-65535> | default}

Configures the delay time between Hello packets on this interface.

The OSPFv3 Hello Protocol is responsible for establishing and maintaining adjacencies (i.e. connections) between neighboring OSPFv3 routers.

For broadcast networks, the Hello is also used to dynamically discover neighbors.

Important - For a given link, this value must be the same for all OSPFv3 routers.

Range: 1-65535 seconds, or default

Default: 10 seconds for broadcast networks, 30 seconds for point-to-point networks

ip-reachability-detection {off | on}

Directs OSPFv3 to start BFD (Bidirectional Forwarding Detection) for each neighbor, from which it hears on this interface.

The BFD session is started only after OSPFv3 transitions to 'Full' state with the neighbor.

Once the BFD session is up, OSPFv3 responds to changes in BFD state.

If a neighbor does not have BFD configured or it does not respond to BFD control packets, it does not impact OSPFv3 operation.

OSPFv3 can operate with both BFD and non-BFD neighbors on the same interface.

Before you enable this option, see IP Reachability Detection.

Range: off, or on

Default: off

passive {off | on}

Disables (off) or enables (on) passive mode for this interface.

When passive mode is enabled, the OSPFv3 interface does not send Hello packets.

This means that the link does not form any adjacencies.

Passive mode enables the network associated with the interface to be included in the intra-area route calculation rather than redistributing the network into OSPFv3 and having it as an Autonomous System External (ASE) route.

In passive mode, all interface configuration information, with the exception of the associated area and the cost, is ignored.

Range: off, or on

Default: off (The interface sends Hello packets)

priority {<0-255> | default}

Configures the priority used in the Designated Router (DR) election on the link.

When two routers attempt to become the DR, the one with the higher priority is elected.

However, if there is already an elected DR, then it continues as the DR regardless of priority.

This prevents frequent changes in the DR state.

The priority is only applicable to shared-media like Ethernet.

A DR is not elected on point-to-point interfaces.

A router with priority 0 is not eligible to become the DR.

Range: 0-255, or default

Default: 1

retransmit-interval {<1-65535> | default}

Configures the time between LSA retransmissions for this interface.

This value is also used when retransmitting database description and link state request packets.

This value should be much higher than the expected round-trip delay between any two routers on the network.

Being conservative helps avoid unnecessary retransmissions.

Important - For a given link, this value must be the same for all OSPFv3 routers.

Range: 1-65535 seconds, or default

Default: 5 seconds

security ipsec {off | spi <SPI>}

Disables (off) or enables (on) the IPsec for this interface.

See IPsec Routing.

Range: off, or one of the configured SPIs

Default: off

virtual-address {off | on}

Disables (off) or enables (on) VRRP mode for this interface.

Important:

  • Configure this option on VRRP Cluster Members when the given interface is configured as a VRRP interface.

  • Do not configure this option on ClusterXL Cluster Members.

When this option is enabled, OSPFv3 uses the VRRP Virtual IP Address associated with the VRRP interface instead of the physical IP address.

In addition, OSPFv3 only runs when this router is the VRRP Master for the given interface.

Range: off, or on

Default: off
