Issue Description
NE40 uses L2 feature board and connects with MA5200. They can ping through. Operate OSPF protocol, but NE40 and MA5200 cannot establish OSPF neighbor.
Version: VRP3.10-2229。
The case is applied to VRP3.10-042X and VRP3.10-2XXX version.
Handling Process
Configure property routing at VLAN interface of NE40 and MA5200, change VLAN interface as route attribute or Change OSPF network type of interface vlanif 20 interface of NE40 as point-to-point.
Configuration:
1. Change interface vlanif 20 interface of NE40 as route attribute
interface vlanif 20
ip address X.X.X.X 255.255.255.252
property routing
2. Change OSPF network type of interface vlanif 20 interface of NE40 as point-to-point
interface vlanif 20
ip address X.X.X.X 255.255.255.252
ospf network-type p2p
Root Cause
For OSPF in broadcast network, hello packet is sent with multicast, but L2 feature board VLAN interface is not configured with route attribute and then it does not support multicast. OSPF hello packet of two devices cannot be interacted and OSPF neighbor cannot be built.
