Subject: Fixes a bug related to mixed up neighbor events in BGP.
X-Git-Tag: v1.4.0~49
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b21955e05800c3ceedfe39eef605da84285296c7;p=thirdparty%2Fbird.git

Fixes a bug related to mixed up neighbor events in BGP.

Neighbor events related to received route next hops got mixed up with
sticky neighbor node for an IP of the BGP peer. If a neighbor for a next
hop disappears, BGP session is shut down.
