Subject: Add a maxattr regress test that causes the rdomain1 bgpd instance to trip
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=4532df1c40b4df3d7f61b1694d736813cd3e74bf;p=openbsd

Add a maxattr regress test that causes the rdomain1 bgpd instance to trip
over 4096 bytes for a BGP UPDATE message. Check on the 3rd system that the
affected prefixes are properly withdrawn.
