To leave _everything_ unchanged (med and next hop which goes w/o saying
;-)) might even best. Hence go for
neighbor <ip> attribute-unchanged
Of course there are also other implemenations like OpenBGPD and BIRD
(http://bird.network.cz/) which also do support that feature.
You could even do per peer RIB to give each of your customer its own
view. Does work for small to medium sized IXP but has not yet proven to
run for really large IXP.
Best regards,
Arnold
