Routing Commands
245
M4100 Series ProSAFE Managed Switches
show ip route
This command displays the routing table. The <ip-address> specifies the network for
which the route is to be displayed and displays the best matching best-route for the address.
The <mask> specifies the subnet mask for the <ip-address>. When you use the
longer-prefixes keyword, the <ip-address> and <mask> pair becomes the prefix, and
the command displays the routes to the addresses that match that prefix. Use the
<protocol> parameter to specify the protocol that installed the routes. The value for
<protocol> can be connected, ospf, rip, or static. Use the all parameter to display
all routes including best and non-best routes. If you do not use the all parameter, the
command only displays the best route.
A “T” flag appended to a route indicates that it is an ECMP route, but only one of its next hops
has been installed in the forwarding table. The forwarding table might limit the number of
ECMP routes or the number of ECMP groups. When an ECMP route cannot be installed
because such a limit is reached, the route is installed with a single next hop. Such truncated
routes can be identified by a “T” after the interface name.
Metric Type The metric type to advertise for redistributed routes of this type
Subnets Whether OSPF redistributes subnets of classful addresses, or only classful prefixes
Dist List A distribute list used to filter routes of this type. Only routes that pass the distribute
list are redistributed
Number of Active
Areas
The number of OSPF areas with at least one interface running on this router. Also
broken down by area type
ABR Status Whether the router is an area border router. A router is an area border router if it has
interfaces that are up in more than one area
ASBR Status Whether the router is an autonomous system boundary router. The router is an
ASBR if it is redistributing any routes or originating a default route
RIP
Split Horizon Mode Whether RIP advertises routes on the interface where they were received
Default Metric The metric assigned to redistributed routes
Default Route
Advertise
Whether this router is originating a default route
Distance The administrative distance for RIP routes
Redistribution A table showing information for each source protocol (connected, static, BGP, and
OSPF). For each of these sources the distribution list and metric are shown. Fields
which are not configured are left blank. For ospf, configured ospf match parameters
are also shown
Interface The interfaces where RIP is enabled and the version sent and accepted on each
interface
