What is OSPFv3 address family?
An OSPFv3 process can be configured to be IPv4 or IPv6. The address-family command is used to determine which AF will run in the OSPFv3 process. Once the address family is selected, you can enable multiple instances on a link and enable address–family-specific commands.
What is router ID OSPFv3?
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.
What is required to implement OSPFv3?
Prerequisites for Implementing OSPFv3
- Complete the OSPFv3 network strategy and planning for your IPv6 network.
- Enable IPv6 unicast routing.
- Enable IPv6 on the interface.
- Configure the IP security (IPsec) secure socket application program interface (API) on OSPFv3 in order to enable authentication and encryption.
How do I enable OSPFv3 on each interface?
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.
Does IPv4 support OSPFv3?
The OSPFv3 process fully supports an IPv4 AF topology and can redistribute routes from and into any other IPv4 routing protocol. An OSPFv3 process can be configured to be either IPv4 or IPv6.
How long is an OSPFv3 router ID?
32-bit
OSPFv3 requires a 32-bit router ID to be assigned before OSPF can be enabled on an interface.
Which of the following will enable OSPFv3?
To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6 ospf area .
Is OSPFv3 compatible with OSPFv2?
Another similarity to the relationship of RIPng to RIPv2 is that OSPFv3 is not backward-compatible with OSPFv2. So if you want to use OSPF to route both IPv4 and IPv6, you must run both OSPFv2 and OSPFv3.
What is the difference between OSPF and OSPFv3?
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….Comparison between OSPFv2 vs OSPFv3.
| S.NO | OSPFv2 | OSPFv3 |
|---|---|---|
| 3. | OSPFv2 have seven link-state advertisement. | OSPFv3 have nine link-state advertisement. |
Which LSA type in OSPFv3 is used for link local updates?
It is the OSPFv3 LSA that contains prefixes for stub and transit networks in the link-state ID. It is also used for IETF NSF (Non-Stop Forwarding).
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 LSA 7 and how it can be used?
LSA Type 7 (NSSA External LSA) packets are used for some special area types that do not allow external distributed routes to go through and thus block LSA Type 5 packets from flooding through them, LSA Type 7 packets act as a mask for LSA Type 5 packets to allow them to move through these special areas and reach the …
What is an LSA type 4?
A type 4 LSA identifies the ASBR and provides a route to the ASBR. The link-state ID is set to the ASBR router ID. All traffic that is destined to an external autonomous system requires routing table knowledge of the ASBR that originated the external routes.
How to configure OSPFv3 for IPv6?
For OSPFv3 Configuration, we will follow the below steps one by one: 1. Enabling Global IPv6 Routing 2. Enabling Interfaces for IPv6 3. IPv6 Address Configuration 4. Configuring OSPFv3 Process
What multicast addresses does OSPFv3 use?
OSPFv3 uses multicast addresses FF02::5 (all OSPF routers), FF02::6 (all OSPF DRs) OSPFv2 Router ID (RID) must be manually configured, still a 32-bit number
What is the difference between OSPFv2 and OSPFv3?
OSPFv2 has two flooding scope, AS wide and area wide but now OSPFv3 has three flooding scopes (noted with the S1 and S2 bits). Here is a list of the similarities between OSPFv2 and OSPFv3:
Why router ID is in IPv4 format for ospv2 and ospv3?
Because for both OSPv2 and OSPv3, Router ID is in IPv4 format. IPCisco is the Winner of 2019 & Finalist of 2020 in “Best Certification Study Journey ” Category!
