We will now look at an industry
initiative called MANRS. It stands for
Mutually Agreed Norms for Routing
Security and this is an industry effort
to ensure best practices for security of
the routing system. MANRS has four
recommendations and you can find those
at the MANRS website. The first one is
to prevent propagation of incorrect
routing information and basically that's
about filtering bgp peers inbound and
outbound. The second one is to prevent
traffic with spoofed source addresses
and that is BCP38, all about unicast
reverse path forwarding. The third one is
to facilitate communication between
network operators. Now this facilitating
communication can be ensuring you know
how to contact the network operation
center of your peers, your transit, your
customers. And also to ensure up-to-date
details in Route and AS Objects and in
the peering database. And the final
MANRS principle is to facilitate
validation of routing information. And
this is Route Origin Authorization using
rpki which we'll talk about elsewhere in
this series. Now let's look at each of
the MANRS principles in a little bit
more detail. This series talks about some
of these principles in more detail
elsewhere but it is useful to summarize
them here for clarity about the MANRS
principles.
