Multi Exit Discriminator (MED) Policy

MEDs received from peers will be ignored by default, unless prior arrangements have been made to confirm the quality of the values.

MEDs are announced by default, using good aggregates and meaningful values based on IGP costs. Peers may decide to honor these MEDs at their discretion.

Prefix Length Filtering

Announcements received from peers are filtered against a list of bogon blocks, as well as by prefix length. The shortest prefix length which will be accepted from any network is a /5, the longest prefix length which will be accepted is a /24. 

Outbound announcements from AS19151 or AS13645 will never exceed /24 in length. All routes announced will be registered in the Internet Routing Registry (IRR) databases under the as-set AS-BBOI.
