Hello, I would like to implement IS-IS as a part of my master thesis. Are there any apparent problems which would prevent successful implementation, political and/or technical? Also I would like to hear opinions of the authors. Implementation timeframe is 2013 (if we live past 21th).

Hello,
We're trying to implement in our RS configuration additional "Collector" table.
After making the changes began to generate the following message to our log file like this and our log file become too large for a very short time :
17-12-2012 13:57:16 <ERR> Pipe collision detected when sending 120.28.62.0/24 to table Collector 17-12-2012 13:57:16 <ERR> Pipe collision detected when sending 120.28.62.0/24 to table Collector
..
Everything other works fine. We would like to understand if there is something wrong in our configuration?
There is a problem that you have many paths for router from BGP to collector table: Standard: RO_149 -> T65050 -> C65050 -> Collector Unexpected: RO_149 -> T65050 -> master -> Txxxxx -> Cxxxx -> Collector You should add import filter for Cxxxx to allow only routes received from associated BGP connection and not the routes received through master table. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

Hello We already started some work on IS-IS [1], although the work was postponed mainly by work on IPv4 / IPv6 merge [2], which is suggested prerequisite for IS-IS, as its use of raw ethernet frames and integrated IPv4/IPv6 topology makes current single-address_family BIRD behavior and internals inconvenient. I would prefer to continue in implementating IS-IS. If you want something similar for your thesis, i would suggest to implement OLSR (RFC 3626) or Babel (RFC 6126), these are protocols that would be nice to have in BIRD but i don't plan to implement them myself, and they could be easily implemented in current BIRD. Or perhaps we could discuss that off-list and find some solution. [1] https://git.nic.cz/redmine/projects/bird/repository/revisions/fed1bceb2cf6d4...

Any movement on this? I'd also be interested in IS-IS. The two links above just go to a login page :-( The dependency on the IPv4/IPv6 merge is only a prerequisite if you want to route both IPv4 and IPv6 simultaneously. IS-IS also has other uses (e.g. trill / SPB / 802.1aq). -- Alex Bligh

Plans hasn't changed. Ondrej is still working on the integrated version of BIRD. First step was OSPF re-design that was introduced in 1.5.0. So we are slowly moving towards IS-IS. Ondrej

As nobody bothered to answer - YES PLEASE ! A lot of Tier-X Carriers today use IS-IS as the IGP as it has nice integration of v4 and v6. Though it'll be interesting how you thought about solving the OSI CLNS/CLNP thing. Bringing a minimal socket support into the kernel or implementing it in userspace/bird? Another thing is that bird currently either supports v4 or v6 depending on compile options - which looses the ability of doing single topology IS-IS with bird. Flo -- Florian Lohoff f@zz.de
