What version of OSPF is used with IPv6?
What version of OSPF is used with IPv6?
version 3
OSPF version 2, introduced as RFC 2328 in 1998, has been one of the most widely deployed interior gateway protocols (IGPs) for intradomain routing. The protocol is extended in version 3 (RFC 2740) to support OSPF in IPv6 networks.
How do I enable OSPF Version 3?
Enabling OSPFv3
- Enter the configure terminal command to access global configuration mode. device# configure terminal.
- Enter the ip router-id command to specify the router ID.
- Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 on the device.
Is OSPFv3 only for IPv6?
Organizations can stick with OSPFv2 for IPv4, and then use OSPFv3 for IPv6-only for a configuration that separates the control planes and the forwarding planes. Organizations can now combine the configuration of IPv4 and IPv6 into a single OSPFv3 process that can work equally well for both IP protocols.
How do I enable IPv6 on OSPF?
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.
What is the latest OSPF version?
OSPF Version 2
Since then there have been several revisions to the OSPF Version 2 standard, in RFCs 1583, 2178, and 2328, with the last of these the current standard. OSPF Version 2 is the only version in use today, so it is usually what is meant when people (including myself) refer to “OSPF”.
Does OSPF support IPv6?
OSPF is a widely used IGP in IPv4, IPv6, and dual-stack (IPv4/IPv6) environments. The OSPF upgrade to support IPv6 generated a number of significant changes to how the protocol behaves.
Which is a difference between OSPFv2 and OSPFv3?
OSPFv2 stands for Open Shortest Path First version 2 and OSPFv3 stands for Open Shortest Path First version 3. OSPFv2 is the IPv4’s OSPF version, whereas OSPFv3 is the IPv6’s OSPF version. In OSPFv2, many OSPF instances per interface are not supported, whereas in OSPFv3, many OSPF instances per interface are supported.
What is OSPF v2?
Open Shortest Path First Version 2 (OSPFv2) is a link-state routing protocol that uses link-state advertisements (LSAs) to update neighboring routers about a router’s interfaces. Each router maintains an identical area-topology database to determine the shortest path to any neighboring router.
How many versions of OSPF are there?
Since then there have been several revisions to the OSPF Version 2 standard, in RFCs 1583, 2178, and 2328, with the last of these the current standard. OSPF Version 2 is the only version in use today, so it is usually what is meant when people (including myself) refer to “OSPF”.
What is OSPF Version 3 for IPv6?
OSPF Version 3 for IPv6. OSPF version 2, introduced as RFC 2328 in 1998, has been one of the most widely deployed interior gateway protocols (IGPs) for intradomain routing. The protocol is extended in version 3 (RFC 2740) to support OSPF in IPv6 networks.
How do I configure OSPFv3 on a Cisco router?
The following steps are involved in the OSPFv3 configuration on a Cisco router: Enable IPv6 routing using the ipv6 unicast-routing command from global configuration mode. Create an OSPFv3 routing process and enter OSPFv3 configuration mode using the ipv6 router ospf process-id from global configuration mode.
What is osfospf version 2?
OSPF version 2, introduced as RFC 2328 in 1998, has been one of the most widely deployed interior gateway protocols (IGPs) for intradomain routing. The protocol is extended in version 3 (RFC 2740) to support OSPF in IPv6 networks.
What is OSPFv3 passive interface in CCNA version 2?
There is one completely optional feature that is relevant to your CCNA version 2 exams: OSPFv3 passive interface. This feature is quite similar in concepts and configuration to its OSPFv2 counterpart. If you want a router not to form OSPFv3 neighbor relationships on an interface, that interface may be made passive.
