From bb97e4622ed6f48e2b8e07f1f94edd03162223a1 Mon Sep 17 00:00:00 2001 From: Christian Franke Date: Sat, 25 May 2013 14:01:35 +0000 Subject: bgpd, zebra: Support NEXTHOP_IPV4_IFINDEX in nexthop_lookup api Since commit ba281d3d040, ospfd uses NEXTHOP_IPV4_IFINDEX routes. The API between zebra and bgpd which is used to query nexthops for recursive routes did not support this nexthop type and therefore, ospf changes (or any other IGP changes which use NEXTHOP_IPV4_IFINDEX) would never trigger any recursive route update.
