From: Rafael Zalamena Date: Thu, 7 Mar 2019 19:44:08 +0000 (-0300) Subject: topotests: add new bfd topology with IPv6 X-Git-Tag: 7.1_pulled~178^2 X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=refs%2Fpull%2F3918%2Fhead;p=mirror%2Ffrr.git topotests: add new bfd topology with IPv6 New BFD topology using IPv6 and multi hop peer to cover more daemon features. This topology also tests BFD integration with BGP, OSPF and OSPF6.
