OSPF run on Fiber Ring
May i know the best solution implement OSPF in Fiber Ring.
Did the OSPF P2P network showing below topology 1 is the best implementation
or using OSPF Broadcast network as showing in topology 2 is better.
What are the pro and cons implement this 2 OSPF network type in this ring topology.
**please take note connectiong between AG DW to OSN SDH is eth-trunk (LACP)**

However, if P2P is used as you depicted, a lot of redundant traffic is generated. For example, when SW2 accesses SW5, SW1 needs to forward the traffic (the traffic direction is marked in red in the figure). And in the broadcast solution, although the intermediate transmission network functions as a Layer 2 switch, the RPF function is used to confirm the next hop (based on the unicast routing table) for forwarding multicast traffic. Therefore, broadcast does not occur. https://support.huawei.com/hedex/hdx.do?docid=EDOC1000163385&id=dc_fd_mrm_0005&lang=en

Dear Brother Liqiang, thank you for your assistance. We take note on this information. Im looking for the answer for this solution in switch perspective.

Well, thank you for your support and trust in our forum, If you have any problems with the transmission network, you are welcome to continue the communication

@Popeye_Wang Here I update the topology 1 for better understanding.
Below are the simulator configuration example on one of the sw ( AG SW1 ) 1) Vlan interface # interface Vlanif200 ip address 192.168.2.1 255.255.255.0 ospf network-type p2p # # interface Vlanif204 ip address 192.168.6.2 255.255.255.0 ospf network-type p2p # 2) OSPF configuration # ospf 1 router-id 1.1.1.1 area 0.0.0.1 network 1.1.1.1 0.0.0.0 network 192.168.2.0 0.0.0.3 network 192.168.6.0 0.0.0.3 # 3) LACP configuration connect to SDH node # interface Eth-Trunk1 description to OSN port link-type trunk port trunk allow-pass vlan 2 to 20 mode lacp-static # interface GE1/0/0 description to OSN SDH1 undo shutdown eth-trunk 1 # interface GE1/0/1 description to OSN SDH1 shutdown eth-trunk 1 # In this topology example, i present 5units AG SW, but in actual implementation is more that 10 AG switch connect in the fiber ring. Based on your 1st reply, put all interface in same vlan and run broadcast network, i have some clarification on this statement. 1) This is consider L3 solution or L2 solution ? 2) Consider run OSPF broadcast network and the number of AG SW more that 10 units, how is the behaviour of OSPF multicast traffic if implement like this? Does it will become broadcast inside the network ? Will cause any abnormal to service ? |
