VRouter and VSwitch

  • Each VPC can have only one VRouter.
  • VRouter does not support dynamic route protocols, such as BGP or OSPF.
  • Each VRouter has only one route table.
  • Route entries in a route table affect all the cloud product instances in the VPC. Currently, the source IP routing rules are not supported by VSwitches and cloud product instances.
  • VSwitches are a layer-3 switch, therefore the layer-2 broadcast and multicast are not supported.
  • The number of instances that a VSwitch can have = 10,000 - the number of existing instances in the VPC.
  • The CIDR block cannot be modified.
