rtnetlink（Linux）中IFA_LOCAL和IFA_ADDRESS的区别
问题描述：
我试着了解IFA_LOCAL和IFA_ADDRESS之间的区别。rtnetlink（Linux）中IFA_LOCAL和IFA_ADDRESS的区别
这是从人：
IFA_ADDRESS raw protocol address interface address
IFA_LOCAL raw protocol address local address
而且我不明白的本地地址和接口地址之间的差异。
有人可以解释我吗？或者给我建议，我可以在哪里找到答案？
THX。
答
此评论来自if_addr.h应该说清楚;
/*
* Important comment:
* IFA_ADDRESS is prefix address, rather than local interface address.
* It makes no difference for normally configured broadcast interfaces,
* but for point-to-point IFA_ADDRESS is DESTINATION address,
* local address is supplied in IFA_LOCAL attribute.
