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.
How do I setup my Quagga router?
Install the quagga package and then configure the Quagga VTY shell. This will create the basic setup for a router. Then, configure the Quagga daemons by editing the file /etc/quagga/daemons and start the zebra and ospfd daemons. Save the file and quit the editor.
Which command is used to enable OSPFv3 on a router?
ipv6 router ospf command
Enter the configure terminal command to access global configuration mode. 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.
What is the length of each OSPFv3 router ID?
32-bit
Interface ID is a 32-bit value distinguishing the interface from other interfaces on the originating router.
What is a function of OSPF Hello packets?
A HELLO packet is a special data packet (message) that is sent out periodically from a router to establish and confirm network adjacency relationships to other routers in the Open Shortest Path First (OSPF) communications protocol.
Which forwarding address is used by OSPFv3 address families learned routes to forward data packets to the next hop router?
OSPFv3 uses a router’s link-local IPv6 address (recall from Chapter 2 that these addresses always begin with FF80::/10) as the source address, and as next-hop addresses.
How does a quagga work?
A system with Quagga installed acts as a dedicated router. With Quagga, your machine exchanges routing information with other routers using routing protocols. Quagga uses this information to update the kernel routing table so that the right data goes to the right place.
What happens if no OSPFv3 router ID is configured?
The OSPF process for IPv6 does not require an IPv4 address to be configured on the router, but it does require a 32-bit value for the router ID, which uses IPv4 address notation. The router ID is defined using the router-id command.
How is the router ID for an OSPFv3 router determined?
OSPF uses the following criteria to select the router ID: Manual configuration of the router ID. Highest IP address on a loopback interface. Highest IP address on a non-loopback interface.
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 OSPFv3 in networking?
OSPFv3 is the Open Shortest Path First routing protocol for IPv6. It is similar to OSPFv2 in its concept of a link state database, intra- and inter-area, and AS external routes and virtual links. It is possible to enable OSPF and OSPFv3 at the same time. OSPF works with IPv4, and OSPFv3 works with IPv6.
Which is IPv4 routing protocol does quagga use?
The IPv4 routing protocols that are provided within the Quagga software are: RIPv1 and RIPv2 OSPFv2 BGP4 Save and apply configuration
Do you need an IP address to use quagga?
An IP address of the router is good enough. network defines the networks your router advertises. The access-list entries restrict vtysh, the Quagga command shell, to the local machine, and deny remote administration. Debian, Ubuntu, and possibly other Debian derivatives require one more step before you can launch the daemon.
How to use quagga for dynamic Linux routing?
Dynamic Linux Routing with Quagga 1 Preparing for OSPF. In our little KVM test lab, there are two virtual machines representing two different networks, and one VM acting as the router. 2 Configuring Quagga. Look in your Quagga package for example configuration files, such as /usr/share/doc/quagga/examples/ospfd.conf.sample. 3 Debian/Ubuntu.
Where are the configuration files in quagga Linux?
Configuration files should be in /etc/quagga, unless your particular Linux flavor does something creative with them. Most Linuxes ship with just two files in this directory, vtysh.conf and zebra.conf.
