标题: 多播静态路由引起的循环题目的解决
一、题目:  在r3和r1之间使用了GRE通道,所有的路由器接口配置为sparse-mode,R4 ip为(1.1.4.4)但R1无法ping通多播源。    二、示意图如下:  multicast source -----R5------R3-------R223----R1--e0  ............................................|  ............................................|  ............................................R4  """"""""""""""""""""""""""""""""""""  三、原配置如下:    R1#mtrace 1.1.15.1 150.100.2.1 239.255.8.8  Type escape sequence to abort.  Mtrace from 1.1.15.1 to 150.100.2.1 via group 239.255.8.8  From source (?) to destination (?)
