Basic configuration of OSPFv3

OSPF (Open Shortest Path First) is a link state-based Interior Gateway Protocol developed by the IETF organization.The user supports the use of the IPv6 protocol.He and OSPFv2 are two independent routing protocols.

1. Basic configuration

The configurations of R1 and R2 are basically the same, here R1 is used as an example:

[R1]ipv6 //Enable routing ipv6 function

[R1]int g0/0/0

[R1-GigabitEthernet0/0/0]ipv6 en //Enable interface ipv6 function

[R1-GigabitEthernet0/0/0]ipv6 add 2001:12::1 64

[R1-GigabitEthernet0/0/0]q

[R1]ospfv3 //Used to create and run OSPFv3 process

[R1-ospfv3-1]router-id 1.1.1.1 //In ospfv3, router-id must be set manually, and this 1.1.1.1 is not an ip address.

[R1-ospfv3-1]q

[R1]int g0/0/0

[R1-GigabitEthernet0/0/0]ospfv3 1 area 0 //The declaration in ospfv3 can only be declared in the interface.

[R1-GigabitEthernet0/0/0]q

II. Configuration result

1. View ospfv3 neighbors

2. View ospfv3 routing table

3. Basic message information

The neighbor establishment of ospfv3 is still carried out through Hello packets, where the source address is the link-local address of the interface, the destination address is the multicast address, and the rest of the information is the same as the Hello packet of opsfv2.The text is basically the same, the hello time is 10s, and the death time is 40s.

4. Similarities between OSPFv3 and OSPFv2

1. Network type and interface type.

2. Interface state machine and neighbor state machine.

3. Link State Database (LSDB).

4. Flooding mechanism.

5. Five protocol packets: Hello, DD, LSR, LSU, LSAck.

6. The routing calculation is basically the same.​
