BGP announce (only) full table

Tue Jan 08, 2013 1:55 pm

Hi,

I have a RB1100, running 5.21. BGP is running with our providers, all is good. My v4 and v6 prefixes are flowing up.

I am trying to contribute my BGP view to BGPMon and NLNOG. On quagga, I had this nicely setup, but since we switched to Mikrotik, I cannot figure this out.

What I need is:
  • I want to establish a session (done)
  • I want to export my entire RIB, all 400k+ , sending it the remote multihopped eBGP (currently only my networks are being announced)
  • I want to announce my v4 routes and v6 routes (currently, the session is over v6, and only my v6 routes are being sent)
  • Of course, accept no announcements from them at all
[sanjeev@MikroTik] > /routing bgp instance print 
Flags: * - default, X - disabled 
 0 *  ;;; For providing Data Collection
      name="default" as=37989 router-id=210.23.3.66

Please help.

Hi,

Answering myself, for future searches.
I want to export my entire RIB, all 400k+ , sending it the remote multihopped eBGP (currently only my networks are being announced)
In the "Instance", not the "Peer", check "Redistribute Other BGP"
I want to announce my v4 routes and v6 routes (currently, the session is over v6, and only my v6 routes are being sent)
After a lot of reading up, this seems not to be recommended, because of next-hop issues. I created two sessions, one for v4 and the other for v6
Of course, accept no announcements from them at all
/routing filter add chain=no-input action=discard 
and then applied this in the Peer, not the Instance.

If someone could validate this?
