[j-nsp] Sending iBGP prefixes to another iBGP neighbour

[Mike Williams]

Hey all,

I could very well either be doing this completely wrong, or attempting to do 
the impossible, but...

We have BIRD on Linux using BGP to send prefixes to the MX104 over a direct 
connection, I need to send those prefixes to an MX80 directly connected to the 
104.

At the 104 end of the 104<->80 peering there is just an export policy, that 
simply matches on "from protocol bgp" and the BGP community assigned the 
prefixes I want, then accept and next-hop self.

In isolation, the policy works.

> test policy blah <prefix>/32
...
...

Policy blah: 1 prefix accepted, 0 prefix rejected


The MX104 never actually advertises any prefixes to the MX80 though.

> show route advertising-protocol bgp <mx80>
... zilch ...


Is there some inbuilt protection preventing iBGP prefixes from being sent to 
another iBGP neighbour?
Or am I just doing it wrong?

advertise-peer-as and as-override have no impact.


Thanks
