Hello,
I have a problem with BGP. So, next config on my Mikrotik (3.17 ver.):
/routing bgp instance print

Mikrotik receive default from “reg_world”, but is not advertise it to peer “vlad”:
[admin@MikroTik] > /routing bgp advertisements print vlad
PREFIX NEXTHOP PEER AS-PATH ORIGIN LOCAL-PREF
[admin@MikroTik] >
If I disable out-filter for “vlad”, Mikrotik advertise all prefixes (for example, prefixes received from peer “Catalyst”) except default. If I add default static route to route list and set “redistribute-static=yes”, Mikrotik advertise all static routes except default. Help me please.
