Routing

Hello,

Have You tried to read the JUNOS fine manual at all?

http://www.juniper.net/techpubs/en_US/junos10.4/topics/reference/command-summary/show-bgp-summary.html

Specifically:

If a BGP session is established in the main routing device, the field shows the number of active, received, accepted, and damped routes that are received from a neighbor and appear in the inet.0 (main) and inet.2 (multicast) routing tables. For example, 8/10/10/2 and 2/4/4/0 indicate the following:

    8 active routes, 10 received routes, 10 accepted routes, and 2 damped routes from a BGP peer appear in the inet.0 routing table.
    2 active routes, 4 received routes, 4 accepted routes, and no damped routes from a BGP peer appear in the inet.2 routing table.

 HTH

Thanks

Alex

I think what niev and the article was saying, in your case, that 0/0/0/0 means you do not have another instance with bgp established. So the rest of the section from the article explains more:

• If a BGP session is established on the main routing device, the field shows the number of active, received, accepted, and damped routes that are received from a neighbor and appear in the inet.0 (main) and inet.2 (multicast) routing tables. For example, 8/10/10/2 and 2/4/4/0 indicate the following:
  • 8 active routes, 10 received routes, 10 accepted routes, and 2 damped routes from a BGP peer appear in the inet.0 routing table.
  • 2 active routes, 4 received routes, 4 accepted routes, and no damped routes from a BGP peer appear in the inet.2 routing table.
• If a BGP session is established in a routing instance, the field indicates the established (Establ) state, identifies the specific routing table that receives BGP updates, and shows the number of active, received, and damped routes that are received from a neighbor. For example, Establ VPN-AB.inet.0: 2/4/0 indicates the following:
  • The BGP session is established.
  • Routes are received in the VPN-AB.inet.0 routing table.
  • The local routing device has two active routes, four received routes, and no damped routes from a BGP peer.

  So in your case, 0/0/0/0 is the equivalent of 2/4/0/0. You dont have another established session, so the 0/0/0/0 is just a place holder value.

  I have to agree with you though, Juniper may not really pride itself as coming up the best explanations. I can site numerous examples where I am left confused and go to somebody else website and get a total understanding.
  

The article provided aarseniev does show the information I am referring by do not explain anything about it.

show bgp summary (When a Peer Is Established)

I have only see those additional number on the SRXs. The MX-80 display the information as I should expect. Below is the output of the same command on an MX-80. It does not have the additional set of zeros 0/0/0/0 .

Those extra zeros does not show up in any of the other commands (e.g. show bgp neighbor), so I am going to assume that they are superfluous.

I have only see those additional number on the SRXs. The MX-80 display the information as I should expect. Below is the output of the same command on an MX-80. It does not have the additional set of zeros 0/0/0/0 . And it should not because we see the routing instance with established neighbors! So we are good here!

Those extra zeros does not show up in any of the other commands (e.g. show bgp neighbor), so I am going to assume that they are superfluous. 

>show bgp neighbor is specific now and not a summary. Since there are no neighbors in a routing instance on the srx and the router, where would you expect to see the missing zeros show up from a command that is looking for neighbors? 

Different commands will provide different information. However if you had a routing instance and you ran the command it would still show you information in a different format, for example:

Table TestRI.inet.0 Bit: 20000
RIB State: BGP restart is complete
RIB State: VPN restart is complete
Send state: in sync
Active prefixes: 0
Received prefixes: 0
Accepted prefixes: 0
Suppressed due to damping: 0

 I am not sending any routes.

BTW,  Could you provide this information:

lab@mxA-1# run show bgp neighbor

Hi there,

The Juniper documentation link I posted DOES have this set of numbers three, not four but this also applies), it is just so wierdly formatted so not anyone can spot them.

0/0/0

I hope the documentation now makes sense to You.

If not I spell it out - the nimbers in Your latest post in red refer to number of BGP routes in INET.2 table.

As long as You don't have BGP "family inet-multicast" routes coming from Your peers, these will be always zero.

HTH

Thanks

Thank you everyone!! I just got what everything was trying to explain. It suddenly click. I appreciate everyones input and willingness to help. Sorry for dragging the conversation this long when everything was explained on the first post.
