tamihiro eaf531eee2 Correctly parse aspath for both bird 1.x and 2.0. 
Due to the change in the output of `show route for <prefix> all` since bird-2.0, this patch is necessary to correctly parse aspaths.
Without this patch, `build_as_tree_from_raw_bird_ouput()` fails with the following exception if the backend is bird-2.0.

```

```

Consequently, `show route for <prefix> (bgpmap)` shows an error icon.

BIRD-LG

This is a looking glass for the Internet Routing Daemon "Bird".

Software is split in two parts:

  • lgproxy.py:

    It must be installed and started on all bird nodes. It act as a proxy to make traceroute and bird query on the node. Access restriction to this web service can be done in file "lgproxy.cfg" (only IP address based restriction for now).

  • lg.py:

    This is the frontend, a web based UI that request informations to all lgproxy.py nodes. The domain and the list of all bird nodes can be done.

  • python-dnspython
  • python-pydot
  • python-memcache
  • graphviz
  • whois
  • traceroute
