Layer 3 Routing Commands 1500
If the longer-prefixes option is specified, then the subnets within an
aggregate are displayed. For example:
show ip route 192.168.2.0 /23 longer-prefixes
The numbers in the brackets indicate the route preference (administrative
distance) and metric respectively. The metric is specific to the originating
protocol. Connected routes have a preference of 0 and static routes have a
preference of 1.
Example
The following example displays the IPv4 address of the default gateway and
the default route associated with the gateway.
console#show ip route
Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static
B - BGP Derived, E - Externally Derived, IA - OSPF Inter Area
E1 - OSPF External Type 1, E2 - OSPF External Type 2
N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2
S U - Unnumbered Peer, L - Leaked Route, T - Truncated ECMP Route
* Indicates the best (lowest metric) route for the subnet.
C 3.0.0.0/24 [0/0] directly connected, Vl10
S U 6.1.0.6/32 [0/0] via Vl20
S U 6.2.0.6/32 [0/0] via Vl20
The following example shows an ECMP route with only one path.
