Simple BGP Configuration: ROS7 + redistributed connected

RouterOS RouterOS beta
1

Hello
I have made some test:

Router with 1 “upstream session” where we receive default route. :eth1
eth2 towards customers (default originate if installed)
eth3: to another router (default originate if installed)
eth4: to another router (default originate if installed)

I upgraded from a working 6.48.5 conf , fully working, no route filters, just I need to redistribute connected + default route.
I upgraded the conf, and I am not able to “redistribute” connected routers nor default route.

I correctly receive the “default route” from the bgp partner in eth1.
I successfully establish connections on eth2,3,4 to other routers.
I receive their routes.
I am not propagatin anything, nor default route, nor locally directed connected routes.
What I am overseeing ?

I’ve built my BGP from scratch on my test machine so this might be egg sucking,

Are you setting the output with

/routing bgp template set output.redistribute=connected,static

(Or setting it in the individual peer)

It looks like route filters are now default deny rather than default accept too. I can’t find any way to do /routing bgp advertisements print

Hello. Yes it is selected. No avail.

Is it possibile that no one noticed this or tested this ?

To originate default route you need to set output.default-originate=…
If you do not have any filter rules but you have specified the chain name, then everything will be rejected by default.

Hello.
Thank you for your reply.
I have read the manual and read the examples.
I have set to originate the default route towards one peer, I have deleted the chain name in the output, with no difference.
nothing is redistributed, nor the connected routes nor the default.
Nothing at all.

If everything is set up correctly it should announce prefixes. Make a supout file and send to support.

This is the relevant part.
the router DOESNT propagate anything, nor connected routes nor default route.
CAn you help me ?


in the wiki:

If the routing filter chain is not specified BGP will try to advertise every active route it can find in the routing table
