Displaying IP configuration information and statistics

Example
Syntax: show ip route summary
In this example, the IP route table contains 35 entries. Of these entries, 6 are directly connected
devices, 28 are static routes, and 1 route was calculated through OSPF. One of the routes has a
zero-bit mask (this is the default route), 27 have a 22-bit mask, 5 have a 24-bit mask, and 1 has a
32-bit mask.
The following table lists the information displayed by the show ip route command.
Clearing IP routes
If needed, you can clear the entire route table or specific individual routes.
To clear all routes from the IP route table, enter the following command.
PowerConnect# clear ip route
TABLE 164
CLI display of IP route table
This field... Displays...
Destination The destination network of the route.
NetMask The network mask of the destination address.
Gateway The next-hop router.
An asterisk (*) next to the next-hop router indicates that it is one of multiple Equal-Cost
Multi-Path (ECMP) next hops for a given route. The asterisk will initially appear next to the first
next hop for each route with multiple ECMP next hops. If the ARP entry for the
next hop * ages
out or is cleared, then the next packet to be routed through the PowerConnect device whose
destination matches that route can cause the asterisk to move to the next hop down the list of
ECMP next hops for that route. This means that if the
next hop * goes down, the asterisk can
move to another next hop with equal cost.
Port The port through which this router sends packets to reach the route's destination.
Cost The route's cost.
Type The route type, which can be one of the following:
•
B – The route was learned from BGP.
•
D – The destination is directly connected to this Layer 3 Switch.
•
R – The route was learned from RIP.
•
S – The route is a static route.
•
* – The route and next-hop gateway are resolved through the ip default-network setting.
•
O – The route is an OSPF route. Unless you use the ospf option to display the route table,
“O” is used for all OSPF routes. If you do use the ospf option, the following type codes are
used:
•
O – OSPF intra area route (within the same area).
•
IA – The route is an OSPF inter area route (a route that passes from one area into
another).
•
E1 – The route is an OSPF external type 1 route.
•
E2 – The route is an OSPF external type 2 route.
