3、P協(xié)議 RIP協(xié)議適用于中小型網(wǎng)絡，有RIPv1和RIPv2 使用UDP進行路由信息的交互，端口號520 RIP支持：水平分割、毒性逆轉和觸發(fā)更新Copyright 2010 Huawei Technologies Co., Ltd. All rights reserved. Page6RIPv1 vs. RIPv2 RIPv1為有類別路由協(xié)議，不支持VLSM和CIDR 以廣播的形式發(fā)送報文 不支持驗證 RIPv2為無類別路由協(xié)議，支持VLSM，支持路由聚合與CIDR 支持以廣播或者組播（224.0.0.9）的形式發(fā)送報文 支持明文驗證和 MD5 密文驗證Copyright 2010 Huaw
