  • 1.  EX3300 Not Advertising Routes in BGP

    Posted 05-21-2015 22:25

    I have confiured BGP on Ex3300 VC but i am not able to adverstise my Connected Networks in BGP, The Conifguration and Output is as below:

     

    It shows Adverstised Prefixes as zero, I have written the below export Policy

     

    set policy-options policy-statement BGP_OUT term 1 from protocol bgp
    set policy-options policy-statement BGP_OUT term 1 from route-filter 10.X.X.X/24 exact---------Connected Network
    set policy-options policy-statement BGP_OUT term 1 then accept
    set policy-options policy-statement BGP_OUT term default then reject

     

     

    The above policy is applied as export in BGP configuration. 

     

    show route

     

    10.X.X.X/24 *[Direct/0] 2d 18:39:06
    > via vlan.50

     

    show bgp neighbor 10.X.X.X

    If you want to advertise connected networks you have to use protocol direct and not bgp as below.

     

    delete policy-options policy-statement BGP_OUT term 1 from protocol bgp

    set policy-options policy-statement BGP_OUT term 1 from protocol direct

    commit

    If i was advertising this route learned via BGP, then my policy would have worked, i didnt realize the Keyword!
