Collecting ECS Network Information

Before configuring policy-based routes for a multi-NIC ECS, you need to collect network information about the ECS.

Table 1 lists the information to be collected for a Linux ECS using IPv4.

**Table 1** Linux ECS using IPv4
ECS	Primary NIC	Extension NIC	How to Obtain
Source	NIC address: 10.0.0.115 Subnet: 10.0.0.0/24 Subnet gateway: 10.0.0.1	NIC address: 10.0.1.183 Subnet: 10.0.1.0/24 Subnet gateway: 10.0.1.1	Obtaining ECS NIC Addresses Obtaining Subnet CIDR Blocks and Gateway Addresses
Destination	NIC address: 10.0.2.12	N/A

Table 2 lists the information to be collected for a Windows ECS using IPv4.

**Table 2** Windows ECS using IPv4
ECS	Primary NIC	Extension NIC	How to Obtain
Source	NIC address: 10.0.0.59 Subnet gateway: 10.0.0.1	NIC address: 10.0.1.104 Subnet gateway: 10.0.1.1	Obtaining ECS NIC Addresses Obtaining Subnet CIDR Blocks and Gateway Addresses
Destination	NIC address: 10.0.2.12	N/A
