Multi-Topology OSPF
by Jafar Al-Gharaibeh 11 Apr '17

11 Apr '17

Lou, Here is the pointer to MT-OSPF (RFC 4915) : https://github.com/AT-Corp/quagga-atc/tree/master It is based off Quagga as of April 2015 I think, put I pushed bug fixes on top that were necessary to have a stable run. This Initial effort started from https://github.com/tomhenderson/quagga-mtr Two main comments about this if we were to bring it in: 1- Keeping track of the multiple topologies was done using the "old" vrf code which was changed to map each topology to an FIB/kernel-routing-table. Significant changes to VRF was introduced to Quagga in mid 2015 which maps VRFs to network namespaces. Some porting effort is needed to decouple topologies from VRFs and map them to multiple routing tables within the same network namespace. At a later date multiple routing table support was added to Quagga so there is a "straight" and logical way to move forward: just map each topology to a routing table. It should have been done that way from the beginning, but since there was no support for multiple tables in Quagga at the time it was easier to just "hack" VRFs. 2- The current implementation supports 128 topology and it statically allocates tables for all of them and maintain them even if you are using very few toplogies or not using any additional topologies other than the default one. A better approach would be to just allocate/maintain those only if/when they are activated. Cheers, Jafar

All - I keep finding and having to fix broken cli issues found by simply running vtysh: sharpd@robot ~/frr> sudo vtysh 2017/04/05 23:08:07 unknown: Ran out of docstring while parsing 'distribute-list [prefix] WORD <in|out> [WORD]' 2017/04/05 23:08:07 unknown: Ran out of docstring while parsing 'no [ipv6] distribute-list [prefix] WORD <in|out> [WORD]' 2017/04/05 23:08:07 unknown: Ran out of docstring while parsing 'no [ipv6] distribute-list [prefix] WORD <in|out> [WORD]' 2017/04/05 23:08:07 unknown: Ran out of docstring while parsing 'distribute-list [prefix] WORD <in|out> [WORD]' Please take a moment to at least *run* vtysh before you push something up for a Pull Request. Martin - I know a month or so back I asked to have some CI coverage of this issue. Is it possible to get something turned on? donald

Re: [dev] Technical steering committee recomendations
by David Lamparter 05 Apr '17

05 Apr '17

Hiya, I'd like to nominate Donald Sharp to be on the steering committee. Donald has been continuously driving the entire project forward, pulling us together into a coherent group with a direction. He is contributing on all fronts - code, review, design and buerocracy; and he has shown that he is able to suggest agreements and ways forward in areas where we have diverging interests in the group :) Cheers, -David
