You should only redistribute your routes to connected BGP next-hops into OSPF as a last resort. Whenever you redistribute routes in OSPF: 1  You're requiring yet another Type4 LSA for every OSPF ASBR (if you're in a multiple-OSPF-area scenario).
A: You need to go to the hairdresser several times per year. How often you get it cut will depend on your budget and of course on the style of your hair. A short haircut will stay in style for a maximum of 4 weeks. When your hair is medium length you should go to the hairdresser about every 5 weeks. If you have long hair you'll need a trim every 6 weeks to avoid split ends. Of course these are just averages.
Trim your hair half an inch every 1-2 months. Neglecting the tips of your hair for too long will cause split ends that will ride up your hairs making it look unkempt. This may seem like it would slow down your hair growth, but it's not healthy to just not get a trim every once in a while.
