Step Description Command Keys
7.1 Add the ability to manage a static IP 
route to the specified subnet 
(optional).
esr(config)# ip route [ vrf 
<VRF> ] <SUBNET> 
{ <NEXTHOP> [ resolve ] |
interface <IF> | tunnel <TUN> | 
wan load-balance rule <RULE> |
blackhole | unreachable | 
prohibit } [ <METRIC> ] [ track 
<TRACK-ID> ]
<VRF> – VRF name, set by the string 
of up to 31 characters.
<SUBNET> – destination address, 
can be specified in the following 
formats:
AAA.BBB.CCC.DDD – host IP 
address, where each part takes 
values of [0..255].
AAA.BBB.CCC.DDD/NN – network IP 
address with prefix mask, where 
AAA-DDD take values of [0..255] and 
NN takes values of [1..32].
<NEXTHOP> – gateway IP address, 
defined as AAA.BBB.CCC.DDD where 
each part takes values of [0..255];
resolve – when specifying this 
parameter, gateway IP 
address will be recursively 
calculated through the routing 
table. If the recursive 
calculation fails to find a 
gateway from a directly 
connected subnet, then this 
route will not be installed into 
the system;
<IF> – an IP interface name specified 
in the form described in Section 
Types and naming order of router 
interfaces;
<TUN> – the name of the tunnel is 
specified as described in section 
Types and naming order of router 
tunnels;
<RULE> – wan rule number, set in the 
range of [1..50];
blackhole – when specifying 
the command, the packets to 
this subnet will be removed by 
the device without sending 
notifications to a sender;
unreachable – when 
specifying the command, the 
packets to this subnet will be 
removed by the device, a 
sender will receive in response 
ICMP Destination unreachable 
(Host unreachable, code 1);
