# The 'a' and 'b' nodes are connected to a 'bridge' node through different
# links. The 'bridge' node configures a bridge across them. It waits forever
# in initrd (stage 1) with networking enabled. 'a' and 'b' ping 'bridge' to
# test connectivity with the bridge interface. Then, 'a' pings 'b' to test
# the bridge itself.
