What is the OSPFv3 router ID?

What is the OSPFv3 router ID?

The Router ID uniquely identifies the router in the autonomous system. By default, Gaia Operating System selects the highest IPv4 address from all configured interfaces. The Router ID is used by the OSPFv3 and BGP protocols.

Is OSPFv3 only for IPv6?

An OSPFv3 process can be configured to be either IPv4 or IPv6. The IPv4 subnets configured on OSPFv3-enabled interfaces are advertised through intra-area prefix LSAs, just as any IPv6 prefixes. External LSAs are used to advertise IPv4 routes redistributed from any IPv4 routing protocol, including connected and static.

How do I enable IPv6 on OSPF router?

To enable the OSPF-for-IPv6 process on an interface and assign that interface to an area, use the ipv6 ospf ospf-process area area-id command in the interface configuration mode. To be able to enable OSPFv3 on an interface, the interface must be enabled for IPv6.

How do you enable OSPFv3 on an interface?

Enabling OSPFv3

1. Enter the configure terminal command to access global configuration mode. device# configure terminal.
2. Enter the ip router-id command to specify the router ID.
3. Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 on the device.

What is the router ID for OSPFv3 router?

OSPFv3 Router ID is still a 32 bit binary number. It is important to configure an OSPFv3 Router ID manually. Use “router-id ” command to configure the OSPFv3 Router ID.

Which is the OSPF command for IPv6 authentication?

To get started we have to use the ipv6 ospf authentication command: Since we want authentication, we’ll select ipsec: First we have to choose a SPI. You can pick any number you like but it has to match on both routers. Let’s pick the lowest available number (256): Now we can choose what authentication we would like, MD5 or SHA1.

How does open shortest path first ( OSPF ) support IPv6?

In order to ensure that Open Shortest Path First version 3 (OSPFv3) packets are not altered and re-sent to the device, OSPFv3 packets must be authenticated. OSPFv3 uses the IPsec secure socket API to add authentication to OSPFv3 packets. This API supports IPv6. Your software release may not support all the features documented in this module.

What do I need to configure IPsec for OSPFv3?

To configure IPsec, you configure a security policy, which is a combination of the security policy index (SPI) and the key (the key is used to create and validate the hash value). IPsec for OSPFv3 can be configured on an interface or on an OSPFv3 area.
