Yes, withdraws should be propagated immediately.  However, the generation of a withdrawl should then subsequently be considered as similar to an advertisement in whatever mechanism you use for avoiding subsequent flap.

Hi

 

With reference to the BGPv4 RFC's, the RFC 4271 has been modified from the RFC 1771, including the withdraw routes in the procedure to control route advertisement frequency.

 

I would like to know :-

1) Shouldnt we advertised the withdrawn routes as soon as possible to aviod black-holes (as identified in the RF1771) ?.

2) Was this change made in light of more frequent route flapping causing withdrawal of routes than actual route withdrawal occuring?
