4.9 Junos Routing – Options

 Prefence: Determine the priority of routes (from many

routing protocol)

 Like Administrative Distance in Cisco

 Some difference compared with Cisco value

 No-readvertise: prohibits the reference route from being

redistributed through routing policy.

 Retain: maintain the route in forwarding table in case of

failure of routing process.

 Aggregate route: summary route before advertise to

another

and from the routing table.

Trang 85

4.9 Junos – Routing Policy

 Import policies: Polices that control how the software

imports routes into the routing tables.

 Export policies: Policies that control how the software

sends routes from the routing table.

 Exact: Means that only routes match the given prefix

exactly

 Orlonger: mach the specified prefix and mask exactly and

all routes that subsets of the prefix
