You are asked to create multiple virtual routers using a single SRX Series device. You must ensure that each virtual router maintains a unique copy of the routing protocol daemon (RPD) process.
Logical systems on SRX Series devices allow the creation of separate virtual routers, each with its unique RPD process. This segmentation ensures that routing and security policies are isolated across different logical systems, effectively acting like independent routers within a single SRX device. For further information, see Juniper Logical Systems Documentation.
To create multiple virtual routers on a single SRX Series device, each with its own unique copy of the routing protocol daemon (RPD) process, you need to use logical systems. Logical systems allow for the segmentation of an SRX device into multiple virtual routers, each with independent configurations, including routing instances, policies, and protocol daemons.
Explanation of Answer D (Logical System):
A logical system on an SRX device enables you to create multiple virtual instances of the SRX, each operating independently with its own control plane and routing processes. Each logical system gets a separate copy of the RPD process, ensuring complete isolation between virtual routers.
This is the correct solution when you need separate routing instances with their own RPD processes on the same physical device.
Configuration Example:
bash
set logical-systems interfaces ge-0/0/0 unit 0
set logical-systems routing-options static route 0.0.0.0/0 next-hop 192.168.1.1
