Abstract:
The DMZ Link Bandwidth draft provides a way to load-balance traffic
to a destination (which is in a different AS than the source) which
is reachable via more than one path. Typically, the link bandwidth
(either configured on the link of the EBGP egress interface or set
via a policy) is encoded in an extended community and then sent to
the IBGP peer which employs multi-path. The link-bandwidth value is
then extracted from the path extended community and is used as a
weight in the FIB, which does the load-balancing. This draft extends
the usage of the DMZ link bandwidth to another setting where the
ingress BGP speaker requires knowledge of the cumulative bandwidth
while doing the load-balancing. The draft also proposes neighbor-
level knobs to enable the link bandwidth extended community to be
regenerated and then advertised to EBGP peers to override the default
behavior of not advertising optional non-transitive attributes to
EBGP peers.
