# TCP convergence layer configuration
#
########################################

#
# interface add [name] [CL]
#
# Add an input interface to listen on addr:port for incoming bundles
# from other tcp / udp convergence layers
#
# For IP-based interfaces, interfaces listen on INADDR_ANY port 4556
# by default. These can be overridden by using the local_addr and/or
# local_port arguments.
interface add tcp0 tcp
interface add udp0 udp

#
# link add <name> <nexthop> <type> <clayer> <args...>
#
# Add a link to a peer node.
# 
# For IP-based links (tcp or udp), the nexthop should contain a DNS
# hostname or IP address, followed optionally by a : and a port. If
# the port is not specified, the default of 4556 is used.
#
# e.g.  link add link1 dtn.dtnrg.org ONDEMAND tcp
#       link add link2 dtn2.dtnrg.org:10000 ONDEMAND tcp

#
# route add <dest> <link|peer>
#
# Add a route to the given bundle endpoint id pattern <dest> using the
# specified link name or peer endpoint.
#
# e.g. route add dtn://host.domain/* tcp0
