Routing Commands

ProSafe M4100 and M7100 Managed Switches

To administratively control the traffic destined to a particular network and prevent it from

being forwarded through the router, you can configure a static reject route on the router. Such

traffic would be discarded and the ICMP destination unreachable message is sent back to the

source. This is typically used for preventing routing loops. The reject route added in the RTO

is of the type OSPF Inter-Area. Reject routes (routes of REJECT type installed by any

protocol) are not redistributed by OSPF/RIP. Reject routes are supported in both OSPFv2

and OSPFv3.

The following shows example CLI display output for the command.

(Switch) #show ip route

Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static

B - BGP 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

C 1.1.1.0/24 [0/1] directly connected, 0/11

C 2.2.2.0/24 [0/1] directly connected, 0/1

C 5.5.5.0/24 [0/1] directly connected, 0/5

S 7.0.0.0/8 [1/0] directly connected, Null0

OIA 10.10.10.0/24 [110/6] via 5.5.5.2, 00h:00m:01s, 0/5

C 11.11.11.0/24 [0/1] directly connected, 0/11

S 12.0.0.0/8 [5/0] directly connected, Null0

S 23.0.0.0/8 [3/0] directly connected, Null0

show ip route ecmp-groups

This command reports all current ECMP groups in the IPv4 routing table. An ECMP group is

a set of two or more next hops used in one or more routes. The groups are numbered

arbitrarily from 1 to n. The output indicates the number of next hops in the group and the

number of routes that use the set of next hops. The output lists the IPv4 address and

outgoing interface of each next hop in each group.

Format show ip route ecmp-groups

Mode

Example

(switch) #show ip route ecmp-groups

via Next-Hop

The outgoing router IP address to use when forwarding traffic to the next router (if any)

in the path toward the destination.

Route-Timestamp

The last updated time for dynamic routes. The format of Route-Timestamp will be

• Days:Hours:Minutes if days > = 1

• Hours:Minutes:Seconds if days < 1

Interface

The outgoing router interface to use when forwarding traffic to the next destination. For

reject routes, the next hop interface would be Null0 interface.

Privileged EXEC
