Can Multiple EIPs Be Bound to an ECS?
Scenarios
Multiple EIPs can be bound to an ECS, but this operation is not recommended.
If an ECS has multiple NICs attached and you want to bind multiple EIPs to this ECS, you need to configure policy-based routes for these NICs so that these extension NICs can communicate with external works.
Operation Guide
This document describes how to configure policy-based routes for Linux and Windows ECSs. For details, see Table 1.
