Is the output of "show pfe route ip" used for finding nexthop and outgoing interface ? is any other table referred for making these decisions ?

So the Packet Forwarding Engine forwarding table is used to find out nexthop and outgoing interface ?

thanks.

Juniper also does provide some answers. A quick search will pull up some inforamtion to answer such questions, for example:

That command shows the IPv4 routes that the PFE currently use to forward packets.
>show route forwarding-table
The routes in the forwarding table are selected from the active routes in the routing table or those placed there with a policy and placed in a forwarding table in the RE. This table should be very similar or a copy if system is running default configurations.

yes

lyndidon thanks for the explanation but I am a bit confused.

So  Packet Forwarding Engine forwarding table is the one which is used to make the decision right ?

what was the relation with show route forwarding-table ? 

Also there is an entry for slot 0 and slot 1 in "show pfe route ip". Do these slots refer to linecards ?

Hi,

May I request for the configuration appeared in your device?

show pfe route ip displays routes in packet forwarding engine table.

Hi,

Just want to make clear of your question that is why I am asking for the configuration or the result of show pfe route

I do not think you are really reading the explanation carefully. 

The Routing Table is in the Control Plane. Active routes selected from the routing table is placed in a forwarding table which is in the control plane. That fprwardint table is the same forwarding table that is synched with the forwarding table in the Packet forwarding engine. >show route forwarding table reveals the contents of the FT that lives in the Control plane. Please read what I just gave and see if this is any different. Anyways, you can always search junipers website for more information. Or I will allow someoelse to explain much more clearly.

thanks lyndidon. I got this explanation. Sorry as I am not so well versed with Juniper terminologies.

Just was keen to know more : 

1. Is PFE in h/w ? Like we have 2 copies of forwarding table.

2. I do not have the details for the configuration. Any guesses what could be "Slot 0" and "slot 1"
