# Test basic BGP routing with three peers.
#
# This script started with no arguments will start all required process and
# terminate them at the end of the tests.
#
# Preconditons
# 1) Run a finder process
# 2) Run "../fea/xorp_fea_dummy"
# 3) Run xorp "../rib/xorp_rib"
# 4) Run xorp "../xorp_bgp"
# 5) Run "./test_peer -s peer1"
# 6) Run "./test_peer -s peer2"
# 7) Run "./test_peer -s peer3"
# 8) Run "./coord"
#
# Peers 1 and 2 are E-BGP Peer 3 is I-BGP
