OSPF comparison between Cisco and Huawei Routers

Open Shortest Path First (OSPFOpen Shortest Path First) is an open standard-based typical link status routing protocol. OSPF routers exchange and save the link information of the entire network, so as to master the topology of the entire network and calculate routes independently. In the network project, OSPF should also be a dynamic routing protocol that everyone is familiar with. This article compares and learns OSPF from different configurations of Cisco and Huawei routers.

I. OSPF single-zone Interconnection

Cisco:
(1) configure the IP addresses of each interface)
(2) Configure OSPF (take intermediate router B as an example)
RouterB (config) # router ospf 10
RouterB (config-router) # network 10.1.1.0 0.0.255 area 0
RouterB (config-router) # network 10.2.2.0 0.0.255 area 0
 

Huawei:
(1) configure the IP addresses of each interface (2) Configure OSPF (take intermediate router B as an example) [RouterB] ospf [RouterB-ospf-1] area 0 [RouterB-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255 [RouterB-ospf-1-area-0.0.0.1] network 10.2.2.0 0.0.0.255 II. multi-zone OSPF Interconnection

Cisco:
R0 (config) # router ospf 100
R0 (config-router) # network 192.168.1.0 0.0.255 area 1
R0 (config-router) # network 192.168.0.0 0.0.255 area 2
R0 (config-router) # area 1 virtual-link 192.168.2.1

Huawei:
[R0] ospf
[R0-ospf-1] area 1
[R0-ospf-1-area-0.0.0.1] network 192.168.1.0 0.0.255
[R0-ospf-1-area-0.0.0.1] quit

[R0-ospf-1-area-0.0.0.2] network 192.168.0.0 0.0.255
[R0-ospf-1-area-0.0.0.2] quit

[R0] ospf
[R0] area 1
[R0-ospf-1-area-0.0.0.1] vlink-peer 192.168.2.1
[R0-ospf-1-area-0.0.0.1] quit
Note:
1. The virtual connection cannot cross the Stub area.
2. To make the virtual connection take effect, you must configure this command on both ends of the virtual connection: vlink-peer xx and the hello, dead and other parameters configured on both ends must be consistent.

Iv. Common OSPF maintenance commands
Cisco:
View neighbor list
Router # show ip ospf neighbor
View link status database
Router # show ip ospf database
View route table
Router # show ip route
View OSPF configurations
Router # show ip ospf
View OSPF Virtual Connection Configuration
Router # show ip ospf virtual-links

Log-adjacency-changes The meaning is that when the adjacent state changes, Log Information.

Huawei:
View OSPF neighbor Information
[Quidway] display ospf peer
View OSPF Interface Information
[Quidway] display ospf interface all
View OSPF route table information
[Quidway] display ospf routing
View OSPF statistics
[Quidway] display ospf cumulative
Display OSPF Virtual connection information
[Quidway] display ospf vlink
