Discarding full route from peer – and using default route instead
To speed up booting your multi-homed router, you may want to temporarily run with default route, instead of the +600.000 routes you are getting from the peer, which may take up to 30 minutes to load on the router.
# Add static default 0.0.0.0/0 route, necessary since i will not get this route from my full feed
add distance=1 gateway=x.x.x.x
# Add in-going filter to the BGP Peer
/routing bgp peer
set BGPPeerName in-filter=isp1-in
# Allow 0.0.0.0/0 and discard everything else (allowing 0.0.0.0/0 in case you are only getting this route from the peer)
add chain=isp1-in prefix=0.0.0.0/0 invert-match=no action=accept set-bgp-prepend-path=""
add chain=isp1-in invert-match=no action=discard set-bgp-prepend-path=""
