Issue Description
When Configured with a Link State Protocol, Why Can the Local Device Not Establish Neighbor Relationship with the Peer Device?
Solution
When the local device is configured with a link state protocol, first check the type of the interface on the peer device.
  • To set the network type for an OSPF interface, run the ospf network-type command.
  • To set the network type of an IS-IS interface to P2P, run the isis circuit-type p2p command.
The network types of the interfaces on both ends of a link must be the same; otherwise, the neighbor relationship cannot be established.
