[bgpd] Fix typo, which prevented advertisement of MP (non-IPv4) prefixes
Browse files Browse the repository at this point in the history
2007-09-17 Paul Jakma <paul.jakma@sun.com>

	* bgp_open.c: (bgp_capability_mp) We were setting
	  afc_nego[safi][safi] rather than afc_nego[afi][safi], thus
	  failling to announce any non-IPv4 prefixes. Remove the extra,
	  typo-ed character.
	* bgp_capability_test.c: Test that peer's adv_recv and adv_nego get
	  set correctly for MP capability and given AFI/SAFI.
	  Colour OK/failed result so it's easier to find them.
