Your company has an IPv4 Ethernet network.A router named R1 connects your segment to the Internet. A router named R2 joins your subnet with a segment named Private1. The Private1 segment has a network address of 10.128.4.0/26. Your computer named WKS1 requires access to servers on the Private1 network. 
The WKS1 computer configuration is as shown in the following table.
Network  Addresses
IPv4 Address  10.128.64.113
Subnet mask  255.255.252.0
Default Gateway  10.128.64.1
The routers are configured as shown in the following table.
Router ID  Addresses
R1
interface 1
R1
interface 2 (To Internet)
10.128.64.1
131.107.108.37
R2
interface 1
R2
interface 2
10.128.64.10
10.128.4.1
WKS1 is unable to connect to the Private1 network by using the current configuration.You need to add a persistent route for the Private1 network to the routing table on WKS1.
Which command should you run on WKS1？（）
