3.有几个问题问一下，小弟新手，请多指教
(1)Telluride的ＢＧＰ表显示有带
r的，什么原因产生的？
Telluride#sh ip bgp
BGP table version is 134, local router ID is 192.168.1.206
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,

(2)Telluride的路由表如下，为何ping 不通192.168.100.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.100.1, timeout is 2 seconds:

(3)Taos 为什么没学到
192.168.1.220/30呢？并且ping 192.168.75.1不通？

(3)帮忙讲讲ＩＧＰ与ＩＢＧＰ同步问题？
小弟问题多多，请大家多指教！thanks
