Run the display ip interface GEO/D/D command to view statistics about ping packets received on the interface.

BGP/MPLS IP VPNs can only use LDP to construct public network tunnels.

As shown in the figure, OSPF is enabled on all interfaces of the router, in which R4 and R5 can establish OSPF virtual connections.

In an MPLS network, functions such as neighbor discovery, session establishment and maintenance, and label management are implemented by exchanging LDP messages between SRs running the DP protocol. To ensure the reliability of message delivery, all LDP messages are sent and received based on TCP connections.

Deploying port isolation technology in Ethernet can realize Layer 2 intercommunication and Layer 3 isolation, making networking more flexible.

BGP routing policies can control the advertisement and reception of routes.
