eBGP Utils plugin

[ssasso]

I tried to perform some work on a eBGP plugin which I was thinking to call "ebgp_utils".
This plugin should be able to support additional "attributes" for eBGP sessions, like

• AS Override (currently implemented)
• Allow-AS In (currently implemented)
• SOO
• Route Maps / Prefix Lists / Communities
• Password
• ...

Since I was thinking only about eBGP, at least for now, my idea was to add the required attributes under the link->node hierarchy (for the links where the eBGP session will be established):

links:
- pe1:
    vrf: blue
    bgp.as_override: true
  edge1:
- pe2:
    vrf: blue
  edge2:
    bgp.allowas_in: 10

You can find my initial implementation here: https://github.com/ssasso/netsim-tools/tree/plugin_ebgp_utils/netsim/extra/ebgp_utils

Any comment, idea, suggestion (or insult) is welcome ;)

Looks good (a few suggestions coming in an email), but wouldn't it be nicer to implement as_override and allowas_in for any EBGP session, not just for VRF ones?

I was still not able to think about Route Maps / Prefix Lists / Communities.
For now I fixed the implementation following your advices (thanks again :-) ) and adding also support fro BGP Password.

(since this development was "just for fun", I'd keep it in this separate branch for now, unless you think the current implementation could be useful for someone)

By all means submit a pull requests -- it's a nice illustration of how one could extend the capabilities of netsim-tools with a plugin.

Thank you! Ivan

Implemented ages ago ;)
