How to view the routing table on an H3C core switch

Use the display ip routing-table command in the CLI to view the routing table on an H3C switch.

Steps to View the Routing Table

1. Access the CLI Connect to the H3C core switch via console, SSH, or Telnet and log in with appropriate credentials.
2. Enter System View (if needed) Some commands may require you to be in system view:

   CodeCopy system-view

3. Display IPv4 Routing Table To view the IPv4 routing table, use:

   CodeCopydisplay ip routing-table This command shows all routes, including destination network, subnet mask, protocol, preference, cost, next hop, and output interface .

4. Display IPv6 Routing Table For IPv6 routes, use:

   CodeCopydisplay ipv6 routing-table This provides similar information for IPv6 networks .

5. Optional Filters and Details
   • To view routes for a specific IP address:

     CodeCopydisplay ip routing-table ip-address [mask | mask-length] [longer-match]

   • To filter by protocol or view statistics:

     CodeCopydisplay ip routing-table protocoldisplay ip routing-table statistics

   • Add the verbose keyword to see detailed route information .
6. Understanding the Output Each route entry typically includes:
   • Destination/Mask: Network or host address
   • Protocol: How the route was learned (Direct, Static, OSPF, etc.)
   • Preference (Pre): Route priority
   • Cost: Metric for route selection
   • NextHop: Next-hop IP address
   • Interface: Outgoing interface for the route Using these commands, you can monitor and troubleshoot routing on your H3C core switch effectively.
