The IP routing table is a data table stored in a router or a network host that lists all the routes to a particular network destination. On the other hand, the IP address table provides detailed information on the interfaces associated with device, their corresponding IP address and subnet. This helps in troubleshooting the problems with the routers that have multiple network interfaces. Both these tables are available in the Router snapshot page.
OpManager queries the below OIDs and collects the necessary information.
IP Routing Table
| OID Name | OID |
| ipRouteDest | .1.3.6.1.2.1.4.21.1.1 |
| ipRouteIfIndex | .1.3.6.1.2.1.4.21.1.2 |
| ipRouteNextHop | .1.3.6.1.2.1.4.21.1.7 |
| ipRouteType | .1.3.6.1.2.1.4.21.1.8 |
IP Address Table
| OID Name | OID |
| ipAdEntAddr | .1.3.6.1.2.1.4.20.1.1 |
| ipAdEntIfIndex | .1.3.6.1.2.1.4.20.1.2 |
| ipAdEntNetMask | .1.3.6.1.2.1.4.20.1.3 |
If you see no data in the router snapshot page, please check if you get a response for the above OIDs from a MIB Browser. You can find these OIDs in RFC1213-MIB.
