HP Moonshot Switch Module CLI Command Reference
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.
Example: The following shows example CLI display output for the command.
(Routing) #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
Default gateway is 1.1.1.2
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
Example: The following shows example CLI display output for the command to indicate a truncated route.
(router) #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
O E1 100.1.161.0/24 [110/10] via 172.20.11.100, 00h:00m:13s, 2/11 T
O E1 100.1.162.0/24 [110/10] via 172.20.11.100, 00h:00m:13s, 2/11 T
O E1 100.1.163.0/24 [110/10] via 172.20.11.100, 00h:00m:13s, 2/11 T
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.
T 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.
