5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide Code Default Gateway IP-Address/Mask Preference Metric via Next-Hop Route-Timestamp Interface Truncated Codes for the routing protocols that created the routes. IP address of the default gateway. When the system does not have a more specific route to a packet's destination, it sends the packet to the default gateway. IP-Address and mask of the destination network corresponding to this route. Administrative distance associated with this route. Routes with low values are preferred over routes with higher values. Cost associated with this route. Outgoing router IP address to use when forwarding traffic to the next router (if any) in the path toward the destination. Last updated time for dynamic routes. The format of Route-Timestamp is: • Days:Hours:Minutes if days > = 1 • Hours:Minutes:Seconds if days < 1 Outgoing router interface to use when forwarding traffic to the next destination. For reject routes, the next hop interface would be Null0 interface. A flag appended to a route to indicate that it is an ECMP route, but only one of its next hops has been installed in the forwarding table. The forwarding table may 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 are identified by a T after the interface name. 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. Reject routes are supported in OSPFv2. 7-39 show ip route ecmp-groups Report 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 the next hop in each group. show ip route ecmp-groups Parameters None 662
